Segmentation violation at global routing resizer timing optimizations #2035

Description

Hello, I'm using the gfmpw-1b tagged version of the caravel-user-project to harden my macro. I got these crash errors in the Global Routing Resizer Timing Optimizations step:

[STEP 20]
[INFO]: Running Global Routing Resizer Timing Optimizations (log: ../home/yunus/caravel_user_project/openlane/fpga_core/runs/23_11_07_16_58/logs/routing/20-resizer_timing.log)...

Also, issue-survey failed to recognize gf180mcu. What should I do?

Expected Behavior

I was expecting to finish the flow without errors.

No worries about the issue survey, that's fine.

I'm gonna forward this issue to the OpenROAD team to see if they may have a workaround.

Hi, I created a new project but it gives the same errors once again. @donn issue_reproducible.zip
