** Attachment added: "python testcase that (causes xserver SEGV in EXA) and
(python SEGV in UXA) for intel G45 (and probably other cards as well?)"
http://launchpadlibrarian.net/24808658/testcase.tgz
** Summary changed:
- python2.6 crashed with SIGSEGV in *__GI___libc_free()
+ [G45] xserver and/or python2.6 crashed with SIGSEGV
** Description changed:
Binary package hint: python2.6
i was working on a python program that uses the pigment library (same
one as elisa uses). I added a line that loaded another picture using gdk
pixbuf (my program already loads several other images into pixbufs but
after I added this one it crashes). the stack contains python stuff,
pigment stuff, opengl stuff and intel driver stuff (this machine has an
integrated intel G45 chipset).
+
+ I was able to reduce my program down to a minimal testcase. Steps to repro
the bug:
+ 1. run intel G45 (probably worsk on GM45 and other intel chipsets as well)
+ 2. run "python main.py"
+
+ If you're in UXA mode you will get a SEGV in python2.6
+ if you're in EXA mode you will get an xserver SEGV
