[PATCH] gitlab-ci: Only use one process in Windows jobs for compilation

Posted by Thomas Huth 3 years, 5 months ago

The Windows jobs are currently aborting at weird places - and
there's the suspicion that it's due to memory constraints in
the Windows containers. Let's switch to single-threaded compilation
to decrease the pressure on the memory load, and to make the
jobs more deterministic for further investigations.

Could it be possibly caused by the windows version of meson? I once
saw the same build failure [1] on one Windows host with 64GiB memory
so I think it is not due to memory constraints on the build host.
