*maybe related:
Also, I encountered a problem that looks like some memory corruption when using --d:useNimRtl. My program consistently crashed at some string operations, after I replaced strutil.% with strformat.&, the problem went away. The same code runs well without --d:useNimRtl. I don't have time to extract the minimal reproducible example at the moment, will revisit this sometime later.
