Hi!

As we're currently doing lots of the builds for m68k and sh4 on qemu,
we are sometimes seeing issues with multi-threading applications. One
of the affected packages is gettext which is currently configured
with "--enable-openmp" in Debian.

Building gettext with "--disable-openmp" on m68k and sh4 avoids the multi-threading issues we have. With the applied patch in src:gettext,
we could enable the package on the buildds again for m68k and sh4.

If you apply the patch, please replace "NNNNNN" in the patch with
the bug number of this bug report (which is not yet determined).

The patch looks ok, but for completeness please tell me that the
OpenMP issue is also reported.

Thanks.

Yes, the OpenMP issue is currently being worked on. It's basically an issue with the atomics in qemu itself which isn't so trivial to fix. I am working together with the qemu developers to fix these issues. Once we have achieved that, we can remove this work-around again :).

Thanks,
Adrian
