What version of PyOpenCL?
Can you provide a traceback? (Does gdb work on OS X?)
On Linux, you would run the whole thing with "gdb -args python
test_wrapper.py", then "r<enter>", wait for crash, then "bt<enter>"
and paste
the output.
Also, since test_wrapper iterates over all your CL "platforms" (i.e.
GPU and
CPU on Apple) and devices, it would be good to know on which one the
crash
occurs. First, grab the newest PyOpenCL from git, rm build -Rf,
rebuild, then
run "python test_wrapper.py -v". You should see exactly where the
crash
occurs.
The result is always 0.0.
As well it should be--it prints the error norm. :)
HTH,
Andreas
