_In reply to [vkantamn](https://verificationacademy.com/forums/t/fatal-sigsegv-bad-handle-or-reference-at-the-definition-of-coverpoint/30369/3):_

There should be more information that that one line of error message you showed. There is normally information about the process that the segfault was executing on.

If you can runt interactively, use the tb command after the simulation halts.
