Bug Description

Hello

I am getting a segmentation fault while running the script source verif/regress/smoke-gen_tests.sh
VCS version used is this one: U-2023.03-SP1 (I am wondering if the version of vcs used is not correct)

Following is the list of different configuration used:

Hi @khandelwaltanuj
Yes, the VCS version is critical to make UVM work.
We are using V-2023.12-SP1
Can you try with this version?

Hello @JeanRochCoulon ,

With this version the gen smoke seems to be passing.
I seems to be getting warning during make clean.
