Some information about bootstrap-emacs binary:
$ file /home/phracek/rpmbuild/BUILD/emacs-24.3/src/bootstrap-emacs
/home/phracek/rpmbuild/BUILD/emacs-24.3/src/bootstrap-emacs: ELF 64-bit
LSB executable, 64-bit PowerPC or cisco 7500, version 1 (SYSV),
corrupted program header size, stripped
$
If condition valid_pointer_p is set to >= 0 then it segfaults again.
Where can be a problem now?
I don't know, sorry. This requires help from someone who knows about
the structure of ELF executables. I suggested to ask some of Binutils
maintainers to help.
Reason of the failure is probably caused by if valid_pointer_p.
