I have tried removing my own liberty file from EXTRA_LIBS , but it still reproducibly crashes even without my own liberty file in exactly the same way.

maliberty commented 9 months ago

Would you pack a test case without your libs?

maliberty commented 9 months ago

It still has your cells in it

thesourcerer8 commented 9 months ago

issue_reproducible.zip I have removed them from the Verilog now, but they are still in the LEFs. I'll try to remove those as well.

thesourcerer8 commented 9 months ago

issue_reproducible.zip Ok, here is the issue without the cells.

With the last reproducible and OR 41f53d4db9aea7fb40cda4db376fd1591ec4b027 (yesterday) I get no crash.
