• With what OpenCL implemenation (ICD)?
• Could you run with python -m pytest -v --capture=no?

[inducer]

Also, is this a regression, i.e. did 2018.1.x work?

2018.1.1 also had this problem.

This looks like pocl may have an issue, more than pyopencl. Does pocl work with a hello-world-level OpenCL program (in C)?

[yurivict]

Hello-world program from this site works: https://us.fixstars.com/opencl/book/OpenCLProgrammingBook/first-opencl-program/

[inducer]

Could you compile PyOpenCL with tracing and figure out which call fails?
