Describe the bug

When running the latest ORFS (490c569) with patches from #3988 on-top, I get following segmentation fault from OpenSTA.

Removing repair_clock_inverters from flow/scripts/cts.tcl does remove this segmentation fault. I also would like to mention that my design has not a single negative edge clock.

Running cts.tcl, stage 4_1_cts

I built OpenROAD in a custom container according to the documentation based on ORFS 490c5690448ab5cfeb4d04e66a52716a676a2d3c. This is the run-time stage and missing tools from the compile stage.

To Reproduce

vars-SG13CMOS5LTop-ihp-sg13cmos5l-base.sh
run-me-SG13CMOS5LTop-ihp-sg13cmos5l-base.sh

No response

Additional Context

I have seen this issue only with two different types of IHP SRAM macros. I can add the same macro twice and that works. As soon as I add a second, different macro, I get this error.
