Yes, I do, too -- I ran into it yesterday while rebasing patches for posting. FWIW, buildbot sees it, too (snippet from x86_64/-m32 linux):

In fact right now, HEAD is unusable:

$ ./gdb gdb
Segmentation fault
$ ./gdb --version | head -1

I'm not normally one to suggest this, but I think this is an exceptional case. Please consider reverting this patch until this issue is resolved.
