In beignet 1.0.1 on i5-3230M Debian 8 (libdrm 2.4.58, kernel
3.16.7-ckt2-1 with the "whitelist OpenCL registers" patch), the recently
added runtime_alloc_host_ptr_buffer (CL_MEM_ALLOC_HOST_PTR) test often
fails when run as part of the whole set, but not when run by itself.
The backtrace points to this being a CL_MEM_OBJECT_ALLOCATION_FAILURE.
(The error handling then calls cl_mem_delete on the incompletely-set-up
buffer, which fails at assert(mem->ctx).)
$ gdb --args ./utest_run -a
