Could you try rebuilding yelp with USE=debug, FEATURES=nostrip and CFLAGS="-02 -pipe -g" to provide a more helpful trace ? Did you build against Firefox (I see the firefox use flag, just checking)? Does firefox show any issues?
>>Did you build against Firefox (I see the firefox use flag, just checking)? Does firefox show any issues? It was built against firefox and I dont have any problems with firefox. I rebuilt yelp with USE="firefox debug" and CFLAGS="-02 -pipe -g". However the backtrace looks exactly the same.
I also rebuilt glibc and nspr with USE="firefox debug" and CFLAGS="-02 -pipe -g". Here is new backtrace: Program received signal SIG33, Real-time event 33.

sorry for not spotting this earlier, but Yelp isn't segfaulting in your backtraces, it's just waiting for a signal to be sent. Could you execute "handle SIG33 nostop noprint" in the gdb prompt before executing "run" ? Thanks.
Here is backtrace. However I can only reproduce this bug if glibc is compiled with CFLAGS="-march=athlon-tbird -O2 -pipe". If it is compiled with CFLAGS="-O2 -pipe -g" then yelp works fine. Program received signal SIGSEGV, Segmentation fault.

If you have some time to rebuild glibc one more time, could you try with -march=athlon instead of athlon-tbird ? Thanks
Mmm, that free() from ORBit may be related to a bug in at-spi that was fixed around version 1.7.8 and is partially fixed with the patch from bug #132019. So another suggestion would be to try emerging the latest at-spi (1.7.10) and see if yelp keeps crashing afterwards.
If I recompile glibc with -march=athlon I still get this problem. However after I emerged at-spi-1.7.10 I could not reproduce this bug anymore.

I can supply emerge --info if necessary. :)
I've entered bug #145428 to request 1.7.10 go stable.
at-spi is now stable, marking as fixed.
