[solved-ish] hal segfaults in libglib

[Jim6]

hal segfaults every time it is started. The instruction pointer is always the same.

Code: Select all

I have tried the following versions of hal and glib
hal:
0.5.9.1-r3
0.5.11-r8
0.5.12_rc1-r7

glib:
2.18.4-r1
2.20.4

I have run revdep-rebuild many many times at this point

I believe that this thread may be related, but maybe not.

make.conf
dmesg
hald --daemon=no --verbose=yes &> hald.txt
strace hald &> hald-strace.txt
hald --daemon=no --verbose=yes &> hald-strace2.txt


Does anyone have any ideas?

I discovered that I was using gcc-4.1.2, so I'm going to try to switch to 4.3.2 and emerge -e world.

I have already tried re-building hal and glib using gcc-4.3.2, so this is a long shot

Code: Select all

sofabox ~ # gcc-config -l
 [1] i686-pc-linux-gnu-4.1.2
 [2] i686-pc-linux-gnu-4.3.2 *

Well, I have it working, but only with no optimisations:

For posterity:

Code: Select all

~ # gcc-config -l
 [1] i686-pc-linux-gnu-4.1.2
 [2] i686-pc-linux-gnu-4.3.2
 [3] i686-pc-linux-gnu-4.4.1 *

Code: Select all

CFLAGS="-O0 -march=native -pipe -fomit-frame-pointer"

then an emerge -av hal glib


Barely a fix, but it's working and that's good enough for the moment.

I just ran into this problem again upgrading hal.

You don't have to re-build glib with -O0. (only hal)
