[Pkg-opencl-devel] Bug#975931: pocl breaks libgpuarray autopkgtest on armhf: segmentation fault

Dear maintainer(s),

With a recent upload of pocl the autopkgtest of libgpuarray fails in
testing when that autopkgtest is run with the binary packages of pocl
from unstable. It passes when run with only packages from testing. In
tabular form:

                       pass            fail
pocl                   from testing    1.5-7
libgpuarray            from testing    0.7.6-5
all others             from testing    from testing

I copied some of the output at the bottom of this report. There's not a
hell of a lot to use for debugging.

Currently this regression is blocking the migration of pocl to testing
[1]. Due to the nature of this issue, I filed this bug report against
both packages. Can you please investigate the situation and reassign the
bug to the right package?
