I tried to run scrapscript.py with RustPython. It crashed. I reduced the input code with CReduce and then manually from ~4k lines to 21 lines.
No crash. In the full example, I expect the test suite to run. In the reduced example I expect nothing to happen.

#5273 fixed a max_stackdepth calculation bug.
Sorry, something went wrong.
Building from main (5d6d1a6) and running still crashes in the same way.
Reduced further:
# scrapscript.py def read_one() : self = 1 while self: break else: return self {")": 2} read_one()
# scrapscript.py def f() : while 1: break else: return 2 {1: 2} f()
