PostPosted: Tue May 23, 2017 9:55 pm    Post subject: Old Software needs old glibc. seg faults with new glibc Reply with quote

I'm trying to install Altera Quartus 13.1 circa 2013. This tool was likely built with glibc 2.17.

When I run the installer, I get a seg fault in glibc but absolutely no clue which function is being called.

I had this running as recently as 2015 and it was working just fine.

This is the only error I get, from dmesg:
Code:
[19686.184718] QuartusSetupWeb[16764]: segfault at 18 ip 00000000f75ad800 sp 00000000ffb6f984 error 4 in libc-2.23.so[f74b8000+1a4000]


I really don't like running Quartus in my Windows 10 VM, even though it is working...

Does anyone happen to have any idea how I can attack this?

Collect a core file. Examine the backtrace using gdb. You may need to rebuild glibc and/or Quartus with symbols first. If so, see Quality Assurance/Backtraces for instructions on how to configure Portage to save the required information.

Thanks for the reply.

I'm not sure I have time for that. I did run it with gdb, but no backtrace was available, even thought glibc was build with the debug option. I think that means the tool has been fully stripped...

You can run some other Linux in a virtual machine.

Thanks. Thought of that, but I already have a Win 10 VM and don't have the memory for another VM. Who builds a laptop in 2016 that maxes out at 16GB, I mean really?

I really want glibc to be slotted or perhaps have a sandbox or something, but I don't think that can happen.

what does "ldd $NAME_OF_EXECUTABLE" show?

is there a local library directory?
If there is, is there a local libstd++ ?
can you "strace $NAME_OF_EXECUTABLE"

I have Mint in a VM, it takes less than 1 GB when it is fully up. My hungriest VM is macOS, it takes 4 GB. Devuan takes about 300 MB.

You can use file to check whether the file is stripped. You should be able to get a partial backtrace out of libc up to the first application frame even if the application was stripped.

sys-libs/glibc has a USE flag debug which is not what you should be using here. Your phrasing is ambiguous as to whether you set that USE flag or followed the instructions in the link I provided above. In either case, you should also rebuild QuartusSetupWeb with debug symbols.

Run it with LD_PRELOAD=/lib/libSegFault.so
Code:
pigeon@gauss ~ $ cat bttest.c
#include <stdio.h>

int foo(int a) { return *(int*)a; }

int bar(int a) {
  if(a) return bar(a-1);
  else return foo(a);
}

int main() {
  printf("%d\n",bar(10));
  return 0;
}
pigeon@gauss ~ $ gcc bttest.c -o bttest
bttest.c: In function ‘foo’:
bttest.c:3:26: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
 int foo(int a) { return *(int*)a; }
                          ^

It won't fix your problem, but it should tell you where the problem is occurring, stripped executable or not.

I tried it, but the output is mostly greek to me.

I don't know why it complains it can't load the ELF, but then does so anyway. The crash seems to be coming from a glibc call from freetype.

I'm not entirely sure where to go from here.

Code:
env SEGFAULT_SIGNALS="abrt segv" LD_PRELOAD=/lib32/libSegFault.so ./setup.sh
ERROR: ld.so: object '/lib32/libSegFault.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

ERROR: ld.so: object '/lib32/libSegFault.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

Note: You must have the 32-bit compatibility libraries installed for the Quartus II installer and software to operate properly.

The file output of the quartus install utility is:

Code:
file QuartusSetup-13.1.4.182.run
QuartusSetup-13.1.4.182.run: ELF 32-bit LSB executable, Intel 80386, version 1 (GNU/Linux), statically linked, stripped, with debug_info

It complains because you are running a shell script, which likely runs a mixture of 32-bit and 64-bit programs. The diagnostics are probably written when 64-bit helpers run before it gets to the point of running the QuartusSetupWeb installer. You could avoid these messages by running only the installer with this $LD_PRELOAD, not the helper script that runs the installer.

You should probably use addr2line to decode the libfreetype lines. The execution of a program in /tmp looks very strange to me. That is extremely poor practice and really should not have worked at all. Is your /tmp not mounted noexec?

Based on the output so far, it looks like an anonymous temporary program tried to create a PNG format image, failed, and died badly while trying to handle/report the error.

Thanks for replying Hu, I really appreciate it.

You are totally right about running the installer instead of the shell script. Thanks.

I don't have /tmp marked as non executable. Apparently the installer wouldn't work if I did, but I didn't even know that I should, so thanks for telling me about it.

The executable /tmp/brrmOp6N doesn't exist after the segfault so I don't know how to run addr2line on it.

It appears they write it, run it, and delete it. You could try to find a way to capture a copy before it is deleted. You might be able to do this by using gdb to trace into the process, so that gdb stops the program when the signal is raised. However, I wanted you to use addr2line on freetype, not on the Quartus temporary file. Even so, I am doubtful that any information you capture will be useful even if this works. The problem appears to be some sort of incompatibility between their generated file's PNG functions and libfreetype.so.6. Without the ability to inspect it in more detail than is convenient for a proprietary program, your options are fairly limited. You could try to find what version of freetype was current back when this installer was new and test whether using that version allows it to proceed.

Thanks Naib. I'll try installing an old version of freetype on Monday.

Thanks so much Naib!

I built the old freetype, installed it in /opt/lib32, changed the LD_LIBRARY:

Code:
export LD_LIBRARY_PATH=/opt/lib32


And Voila! It's installing as I type!

I really appreciate you taking the time to respond and help me out.

PS: What's even more amazing is, the Altera software itself runs without the special freetype library. It was only the installer (and based on the article modelsim) that need the old freetype.
