SIGSEGV Erro during release #52

Open rotilho opened 3 months ago

rotilho commented 3 months ago

Hello,

First of all, thank you for the amazing work with JOCL.

I'm using JOCL to calculate PoW and I'm encountering some issues during unit tests. Everything works fine until I try to release JOCL resources, at which point I encounter the error below. While I don't need technically to release it during normal execution, I thought it was worth reporting.

Code: AttoWorkerOpenCL Test: AttoWorkerTest

Sorry for the delay, and only a short 'acknowledge' for now: I'll try to allocate some time to look into this. But it does not seem to be super urgent or a super common error (and I've reduced the time that I'm spending for JOCL - it has always been a "spare time" project, and "spare time" is always limited...)
