I would like to bring the bug described here:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=239344
to the attention of this mailing list. In a nutshell, what happens is
that an emacs binary built using the Fedora 7 build system will
seg-fault immediately when run on a Fedora 7 install. The stack trace
shows an assert failing in the glibc malloc code (usually it's
setlocale invoking malloc); it appears that something about the way
the dumper preserves the malloc state between the dumping emacs and
the dumped emacs isn't quite working.
Another theory that is being examined is that somewhere there is a
pointer to anonymous mmaped memory. It seems that prepending
MALLOC_MMAP_MAX_=0
to this line
LC_ALL=C $(RUN_TEMACS) -nl -batch -l loadup dump
works, although there are some conflicting reports about this, also.
Anyway, if we could get some more eyes on this bug, it would probably
help a bunch.
