When too many lines, the code will not be evaluated well

[GreasySlug]

Describe the behavior When the number of lines are more than 245, subsequent lines are not evaluated. I used " evaluated", but it is not accurate.

Reproducible code

a_1 = 1
...
a_243 = 1
print!  "Finished"

Expected behavior display "Finished"

Current behavior don't display it

Screenshots (optional)

OS Windows 10

Additional context

I think parse, codegen, etc. are working well. However, the CPython command/instruction seems to be wrong.
