@eder-matheus FYI, I have provied a confidential test-case to @maliberty

@oharboe Could you try this branch: https://github.com/eder-matheus/OpenROAD/tree/ppl_fix? I think it should fix this error you're facing.

Checking that your fix is in...

@eder-matheus FYI, @maliberty has a testcase that still fails with your fix.
