Hello openlane2 community, I am currently trying to debug an issue within the OpenROAD.Floorplan step where OpenRoad segfaults. Based on the Stacktrace I can pinpoint the problem being the LibertyReader, the makeTableAxis function to be precise. Since I am using the Nix setup I was wondering if there was a way to set up an environment where I can launch OpenROAD using gdb, just so I can get the offset within the Liberty file to see where the problem lies. Here is the stacktrace:

I don't use nix but cmake with

-DCMAKE_BUILD_TYPE=Debug

will setup a debug build. If you can share a test case you can open an issue in the OR Github
