By the way, you will notice that before crashing, the debugger stopped with : > thread_db_get_info: cannot get thread info: generic error > (gdb) continue > Continuing. > > Program received signal SIGSEGV, Segmentation fault. This happens just after I double-click "New Printer". Only when I type continue does it proceed to segfault (of course, without debugger, I go straight to gnome crash handler).
The bug disappears with CFLAGS="-march=k8 -O0 -pipe -g", I'll try with -O1. I'll also try the 0.31 ebuild.
Back with -O2, gnome-cups-manager-0.31 reproduces the bug
(In reply to comment #4) > Back with -O2, gnome-cups-manager-0.31 reproduces the bug > -O1, the bug is still here... Would some flag filtering be an acceptable solution ?
> -O1, the bug is still here... Would some flag filtering be an acceptable > solution ? joker on #gentoo-bugs told me it was (thanks!), so goes 2 patches, one for 0.30 and one for 0.31. They append -O0 to the cflags if arch is amd64. Also I reported it upstream : http://bugzilla.gnome.org/show_bug.cgi?id=350054
Created attachment 93492 [details, diff] append -O0 in gnome-cups-manager-0.30 cflags
Created attachment 93493 [details, diff] appends -O0 in gnome-cups-manager-0.31 cflags
amd64 specific changes are up to the amd64 team
it's fixed, thanks Bruno!
this really really needs to be reported upstream and fixed there. -O0 is rife with code generation problems and basic things like inlining will fail to work in subtle ways. i won't reopen since it's your funeral, but please consider it.
