While using mem_trace.so, I see this assertion error for an application.

Don't know how to debug more. There is no problem with opcode_hist. I am using 1.5.3 version. Any idea about that?

What is the application? Do you see the same issue with older versions of nvbit? Thanks.

The application is gromacs, but at the moment, I will close the issue as there are some steps behind that which I have to fix.
