When I emerge media-sound/audacity-1.2.1, it (and its dependencies) emerge fine, but it segfaults on startup.

Please try audacity 1.2.4, ebuild on bug #113948
I tried audacity 1.2.4 from the ebuild on bug #113948 and it also segfaults. From gdb: Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 2199049904128 (LWP 18109)] 0x00000200013b2768 in g_type_is_a () from /usr/lib/libgobject-2.0.so.0
Oh. I don't think anyone in audacity development has an Alpha, so this won't have been tested, and could even be a wxGTK problem. Can you try starting it as $ LANG=C audacity so as to force a base locale (find out if it's a unicode issue somewhere)
I tried $ LANG=C audacity with v1.2.4 and it still segfaults in the same place. If you want me to try anything else, I'd be happy too. A week from now, when I'll have a lot more free time, I'll go through the code and see if I can fix whatever is causing the segfault.
1.2.4b in cvs. Please try it.
(In reply to comment #6) > 1.2.4b in cvs. Please try it. Tried it on alpha, and this time I got a different segfault.... Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 2199023410768 (LWP 561)] 0x000002000090c2c8 in CoordArray::DoCopy () from /usr/lib/libwx_gtk-2.4.so
I was reading the list of dependencies[1] on the audacity site[2] and found the following: "Audacity 1.2 needs wxGTK 2.4, compiled without the gtk2 or unicode options. (Future versions of Audacity will support newer wxWidgets and GTK libraries.)" Then I checked what USE flags wxGTK was compiled with and found +gtk2. I'll recompile wxGTK and audacity without the gtk2 use flag and post the results. My system is somewhat slow so, it will be a few hours. Also, Debian/Alpha has audacity stable on alpha w/o any source code patches.

> I'll recompile wxGTK and audacity without the gtk2 use flag Recompiling wxGTK-2.4.2-r4 and audacity-1.2.4b with USE="-gtk2" didn't work. I got the same segfault as in Comment #7 I'm going to try audacity-1.2.1 and 1.2.3 again as wxGTK was compiled with +gtk2 and -wxgtk1 when I tested those version before. If that fails I'll try a newer wxGTK 2.4.
emerge'ing audacity-1.2.4b and wxGTK-2.4.2-r4 with USE="-gtk2 wxgtk1 debug" and FEATURES="debug" creates an audacity binary that doesn't segfault on startup ( Screenshot: http://cs.ubishops.ca/~tcort/audacity-alpha.png ).

The bug was caused by a buggy wxGTK on alpha (see bug #170914 for details). I was able to test successfully the latest 1.3.2-r1 audacity version against the wxGTK-2.6.4.0 (will be in portage very soon). So the question is: are the people involved in this bug still want to use audacity in alpha? In this case, I'll happy ~alpha it. If not, I will mark this FIXED but give no keyword at all. Thanks.
New glibc-2.5 fixes the problems with wxGTK. I mark this as FIXED and leave audacity without a keyword until someone request it (in another bug). Thanks.
