Source: pocl Version: 1.8-1(Filing this as something to refer to when I disable those tests; it may or may not actually be worth fixing.)
Since some time in August, all the packages that use pocl for their autopkgtests have been failing on armel/armhf (but not arm64) with either
Assertion `td->printf_buffer != NULL' (libgpuarray, theano, examl) or Fatal Python error: Aborted (pyopencl, gpyfft). However, build-time tests using it (pocl itself, pyopencl) pass.
