Hi,
I have been batch testing OpenCL programs and have encountered a number of
cases where pocl performs unusually.
The first is when compiling a kernel with undefined symbols. In this case,
the compiler should error, however, with pocl, the compilation completes
successfully, but the program then crashes due to a symbol lookup error
when trying to run the kernel. I have produced a standalone script here:

this email)
Secondly, there are cases where the program silently crashes during kernel
execution with an error message. Example:
http://paste.ubuntu.com/25031556/ (additional examples in the footer of
this email)
In the above case, the kernel performs a mod zero operation which in the
spec is undefined, though the kernel completes on NVIDIA/Intel OpenCL
implementations.
Cheers,
Chris
