DRC crash

[mguthaus]

I am trying to run DRC with the MOSIS SCMOS DRC deck but I get the following crash. My command line and design are included: klayout -b -r drc_SCMOS.lydrc -rd input=pinv.gds

Hi Matt,

thanks for the test case and the stack trace. I'll try to debug that.

Best regards,

Matthias

Hi Matt,

I could debug and fix the issue. I'm afraid there is no quick workaround, but I'll release the fix with 0.27.4 soon.
