Even --pdump is *NOT* safe if exec-shield-randomize is set to 1.
It rolls over and dies (even a ./xemacs -vanilla --kill) with a
SIGSEGV. I'd report more, but it's slow going, as gdb doesn't seem
to like the way things move around...
echo 0 > /proc/sys/kernel/exec-shield-randomize
works around it. I'll post more soon as I figure out what's going on.
Also, it only dies if you had a stray 'LDFLAGS=-pie' in effect.
I've opened
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=111183
regarding the gdb issue (it flames out if program linked with -pie).
So this is the same bug (in essence) that I already mentioned once with
the exec-shield '-pie' support.
