gegl segv

Roundball
I'm having some difficulty building gimp 2.94 from the current development
tarballs. In fact I have the same issue with git latest:

uname -a
Linux onion 4.4.36-8-default #1 SMP Fri Dec 9 16:18:38 UTC 2016 (3ec5648) x86_64
x86_64 x86_64 GNU/Linux


I build babl, gegl,then libmypaint without errors.

`make gimp` fails at creating icons

running gegl on the command line SEGVs

I tried building on my laptop (also OpenSUSE leap 42.2) and it builds without
error.

running 'valgrind  gegl ../gimp/icons/Symbolic/12/gimp-linked.png invert-gamma`
gives me:

gegl segv

Roundball
Update:

It seems I have a heisenbug. If I run 'gegl --list-all' on the command line it
SEGVs, however it runs without error under gdb, valgrind or strace. Adding in a
few g_message lines it seems it happens at g_module_open() in gegl_module_open()
when trying to open svg-load.so. I'm guessing it's not necessarily this code
which is at fault as memory could have been stomped on elsewhere, but I'm a bit
stuck as to how to progress further.

I can't say I'm much the wiser yet, but running 'LD_DEBUG=libs gegl --list-all'
gives me the following amongst the outut:

followed by a segmentation fault.

Am I right in thinking the proprietary nvidia drivers may be the issue here?

I can confirm that gegl runs fine with the nouveau driver and segfaults with the
proprietary video drivers. Inly it seems with nouveau my monitor isn't detected
properly so I can either have one or the other

Hi,

Could you open a bug report?
https://bugzilla.gnome.org/enter_bug.cgi?product=GEGL
This will likely be more efficient than on the gimp-user mailing list. :-)
Thanks!

Jehan

If anyone else runs up against this the fix is to preload the libraries in the
right order:

export LD_PRELOAD="/path-to/libpthread.so /path-to/libGL.so"
