1) Please specify the version and revision of dev-python/pygtk in the summary. 2) You appear to have two versions of dev-lang/python installed - in which one did you run `import gtk'? 3) Also, did you run python-updater after installing dev-lang/python-2.5*?
I have encountered the same problem with pygtk. It is fixable in my case by reducing optimization level to "-O1" or adding "-fno-schedule-insns" to CFLAGS. Looks like there is a high chance that it is caused by an invalid code generation problem in gcc 4.3. This might be interesting to investigate before gcc 4.3 stabilization. Unfortunately I don't know ppc64 assembly yet and building pygtk is a major pain on ps3 (gcc uses swap extensively and build takes a huge amount of time).

*** Bug 272214 has been marked as a duplicate of this bug. ***
More info present now. Assigning to maintainer and CC'ing toolchain and ppc64 since it might be a misscompilation.
A small update to this bug if anybody is interested. The problem is somewhere in the huge autogenerated file 'gtk.c' (4MB, 120K lines). I had a hope to use a new '#pragma GCC optimize' gcc 4.4 feature to bisect this file and pinpoint the place where the invalid code is generated. But the bug is not reproducible with gcc 4.4.0-r1 anymore. That said, when compiling this huge file, my PS3 swap quite heavily and it takes insane amount of time to build pygtk. So it is not very productive for me to do any kind of experiments with this bug. Let's hope that gcc 4.4 stabilizes soon on ppc64 :-)
what about pygtk 2.14 ?
(In reply to comment #6) > what about pygtk 2.14 ? For me this problem is reproducible with any version of pygtk in portage and any gcc 4.3.x (just tested 4.3.4 too). But I would surely like to get a confirmation from somebody else. Because this looks like a rather serious problem and showstopper on ppc64, unless it only happens in my configuration (maybe running gcc in low memory conditions somehow triggers it, and having enough memory would solve it). On the other hand, gcc 4.4 seems to generate much faster code for cell PPU (up to ~20% speedup or even more on some applications when compared to gcc 4.3 without "-fno-schedule-insns" workaround). So I'm not going to go back to 4.3 anyway.
Maybe we could close this now that gcc-4.4 is in stable... :-/
(In reply to comment #8) > Maybe we could close this now that gcc-4.4 is in stable... :-/ > you are mistaken, ppc* doesnt have gcc-4.4 stable
True :-|, sorry for the noise
(In reply to comment #10) > True :-|, sorry for the noise > now it is :) closing as solved by gcc-4.4
