I created two workloads by profiling a different kernel each time and tried to compare the performance counters between the two kernels using the following command:
omniperf analyze -p workloads/vcopy_vecCopy/mi200/ -p workloads/vcopy_vecCopy_nocheck/mi200/
This fails with the following error after printing the "System Info" panel (I have intentionally changed the full path to my omniperf install, but this does not change the stack trace otherwise):

omniperf v1.0.6 was installed from source using instructions in this repo's documentation without any trouble.
To reproduce, I took the vcopy.cpp example from this repo and added new kernel called vecCopy_nocheck where I just commented out the check for array bounds. I also added a call to launch this kernel. My updates can be seen in the following diff:
