Testing for OSVVM 2020.12 release was done on RivieraPro 2020.10 and ModelSim 2020.01. Unfortunately I did not test with QuestaSim 2020.04 (my licenses are for a machine that I just finished setting up today).
There appears to be a subtle bug in QuestaSim that causes a SEGV Fatal when doing Burst Transfers (such as TbAxi4_MemoryBurst1). I found a simple work around. So at this point all is well.
The updated release 2020.12a is specifically to address this issue.
