Created attachment 182986 [details] core dump of gdb
Filled in an upstream bug: http://sourceware.org/bugzilla/show_bug.cgi?id=9892
can you double check it isnt a Gentoo patch by re-emerging gdb with USE=vanilla
It was indead with USE=-vanilla but I have activated that USE-flag now. Anyway, I am not sure if I can reproduce that. It was just a random crash while debugging. I'll report back when I got the next one.
Can you give us a way to reproduce this bug? Something that happens randomly isn't anything we can test against.
No, I haven't had this crash again. But I have the core dump, you should be able with the core dump together with the debug symbols to see everything. Have you looked at the specific code (from the backtrace I posted)? I will post again if I have another crash but not much I can do otherwise. I am not really familiar with the GDB code, so I don't know if I could see the bug from that backtrace related code (but had no time to look at it yet).
