[bug-gettext] msgfmt segfault under qemu-arm, Jessie only

The `msgfmt` executable segfaults only under `qemu` (`armhf`; other arches untested) and only in Debian Jessie (package v. 0.19.3-2).

    # schroot -u root -c jessie-armhf-sbuild -- \
        qemu-arm-static /usr/bin/msgfmt
    qemu: uncaught target signal 11 (Segmentation fault) - core dumped
    E: Child terminated by signal ‘Segmentation fault’

The same thing works fine in Ubuntu Trusty, so my first thought was to rebuild that package v. for Jessie. However, that version segfaults, too. So, apparently not a regression in `gettext`.

I also tried attaching a debugger, remotely, as required by `qemu`, but this didn't work well; log below. Maybe it's qemu that's crashing.

At least one other person has run across the `msgfmt`/`qemu` problem. He believes it's due to `pthreads`, but if so I'm surprised not many more have encountered it. Link:


Have list members encountered this before? Any advice on where to start digging next? Thanks-
