While trying to debug emacs-24 on HPPA (see bug #570708), I'm getting: esketra:~> gdb /usr/bin/emacs-24 GNU gdb (Gentoo 7.9.1 vanilla) 7.9.1 Copyright (C) 2015 Free Software Foundation, Inc.

Sorry, I forgot to add: This happened after a glibc update. Unfortunatly, I did not have gdb installed prior to issue #570708, so I can only guess that the core problem comes from the new glibc.
threads on hppa and debugging emacs ... that'll be fun can you check gdb-7.8 and gdb-7.10 versions and see if they also fail ?

Both are masked on HPPA, here's what happened with 7.8.2: ut@esketra ~ $ gdb /usr/bin/emacs-24 GNU gdb (Gentoo 7.8.2 vanilla) 7.8.2 Copyright (C) 2014 Free Software Foundation, Inc.

Ahhhh!!! gdb 7.10.1 works: esketra:~> gdb /usr/bin/emacs-24 GNU gdb (Gentoo 7.10.1 vanilla) 7.10.1 Copyright (C) 2015 Free Software Foundation, Inc.

(gdb) From my point of view, this bug can be closed and gdb 7.10.1 should be unmasked on HPPA ;-)
we can probably just stabilize 7.10 now
amd64 stable
x86 stable
sparc stable
alpha stable
ia64 stable
arm stable
ppc stable
Stable for HPPA PPC64. Closing.
