Compilation Error - Githubissues

Hello. I'm using a Raspberry Pi 3 to optimise some code. I've already run some test programs like summing two arrays, etc. Now, I'm stuck with the following error.

This happens even in a kernel that had already worked. The error returned by OpenCL is CL_COMPILE_PROGRAM_FAILURE (-15).

Any ideas? Thanks in advance.

Edit:

Sometimes, the error is this one...
