It is nice :).
Actually I found more puzzling thing. If I run configure with the same
options as I described earlier but define CFLAGS variable like this
CFLAGS="-O3"
compile emacs source and run emacs within gdb:
(gdb) run -Q -D
or
(gdb) run
it don't segfault.
(bzr revno && bzr revno --tree: 100061)
May be there are some tests to check compiled executable?
