Hi I appear to be suffering from this bug here:
http://www.nabble.com/-Bug-libc-4438--New:-vfprintf()-segfault-with-multibyte-string-and-long-precision-t3669503.html

As are a couple of ther people using similar setups.

I'm totally in trouble, I can't downgrade my glibc and theres no version in ...

After an overnight emerge -uND system I found I had this 'could not compile exe' issue.
I tried various other suggestions on here, all the older compilers etc
When I ran binutils-config I realised I wasn't using the latest version.
Switching to the most recent compiler, then the most recent binutils ...

My amd64 system fails on an emerge of libXdmcp, it gives me this lot any ideas?:

if /bin/sh ./libtool --tag=CC --mode=compile x86_64-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I. -I. -I./include -I./include -mtune=k8 -march=k8 -O2 -pipe -fomit-frame-pointer -MT AA16.lo -MD -MP -MF ".deps/AA16.Tpo" -c ...

The solution for this is to enable the support in the kernel for IA32 emulation and IA32 a.out support under Executable file formats / Emulations

Yeah me too, exactly the same

I did a few things recently and I'm not sure which broke it, so let me start at the beginning.
I got a new CPU, an AMD64.
So, changed my CFLAGS for k8 and make.profile for amd64 recompiled the kernel and emerged a few packages.
Portage, baselayout, qt, bash and started kde.

During the kde emerge it ...

I was just searching for help with the same error.
When I saw this I checked my disk space.
Guess what, full. Doh!

Me too, did you ever find a solution for this?

[I've mashed my portage and python somehow, managed to mount and run a python on a samba mount to another box by adding it to ld.so.conf and running ldconfig, but I now get this when trying to do anything portage]

I'd really rather not reinstall this ...

I just tried this emergency repair, but it's broken it worse I think.
Before I just had a missing symbol in libsandbox, now I get this:
/usr/bin/python: error while loading shared libraries: libpython2.3.so.1.0: cannot open shared object file: No such file or directory

I think it's well and truely ...

I just did an emerge gcc (unstable) on each of my machines which recompiled glibc (2.3.4.20040808) Now it gives me the error "checking for suffix of object files... configure: error: cannot compute suffix of object files: cannot compile" whatever I try to emerge.
First I tried gcc-config to go back ...
