Application crash when opening layout with coded PCell Instances
Hi,
I have coded some PCells and created a layout using instances of a few of these PCells. When I try to re-open the layout file the application gets stuck on loading and when I click cancel, a window opens showing a bug report.
I have included the bug report below.
Exception code: 0x20000016
Program Version: KLayout 0.26.7 (2020-07-07 r28bf5259) AMD64

I modified my PCell code and it works fine now.
I think my PCell code was just way too inefficient.
Hard to say from the stack trace ...
The crash may have different reasons. It's not difficult to product a crash when using wrong layer indexes etc. I'm trying to turn them into meaningful messages when I find one, but there are still too many ways to crash the application.
