I tried again with the same kernel, and the crash was still there.
I've updated my kernel to that version, and the crashes disappeared.
I reverted to the previous kernel, and the crashes disappeared too...
The update also brought along other system components, but it might
be that there was just something broken in my gdb build. I don't
have that particular binary any more.

just the usual: configure CFLAGS="-g3 -O0" && make

Ah, I ran autoconf. The tests now run, but I get intermittent failures. Tested
in a loop with:
$ (set -e; while true; do make check RUNTESTFLAGS="--directory=gdb.btrace"; done)
I got one time:
