Could you provide the steps to reproduce the issue and your Julia version? Perhaps a minimal working example that triggers this?

Thank you for your reply. I actually solved it. I always use @inbounds for the for loops. Because of that it did not throw bounds error and tried to acces non-allocated position, so eventually crushed. So, I cleared all @inbounds (there were around 80 of them ) to get error location.

The automated way to do this is to start julia with --check-bounds=yes :grin:. That’s how package test suites get started, too.
