12/06/2021, 8:45 AMYou should package a test case and file an issue. Its hard to guess from the stack trace what is wrong
Matt Liberty
12/06/2021, 8:46 AMdo you have any warnings in the log?

12/06/2021, 9:02 AMThing is ... I don't even know how to reproduce it in gdb, I only got the stacktrace off a core file. OpenLane sets up so many thing in the environment pointing everywhere that calling openroad manually in the same way is very hard to achieve 😕

12/06/2021, 9:06 AMNote that this isn't the official git hash from openlane. When I was using the official git hash, it was crashing way earlier in STA when calling some spdlog functions. Looking at the git log I saw that master had some fixes related to spdlog so I updated and that indeed fixed that crash in STA.
