Ok, so now what I find is that running clinfo under heaptrack causes a
segfault. I can get some more information if I run `heaptrack -d clinfo`.
Sadly, the segmentation fault happens inside the proprietary Intel OpenCL
platform. I suspect that one of the LD preloads is interfering. The backtrace
is:
#0 0x00007fffbb08abc1 in ?? () from
/opt/intel/opencl-1.2-6.4.0.25/lib64/libintelocl.so
#1 0x00007fffbb0082fe in clGetPlatformInfo () from

I'm not sure if it's easy to reproduce, but it's probably going to need the
Intel OpenCL ICD and the use of the open-source ocl-icd for libOpenCL.
