[issue42873] Exponential time and space requirements for compilation of nested try/finally blocks

[issue42873] Exponential time and space requirements for compilation of nested try/finally blocks

Mark Dickinson added the comment: For extra fun, you can add `break` and `continue` paths into the mix to get a 5-fold instead of 3-fold code size increase per level of nesting. It's still contrived code, though. Example where do_cleanup() ends up with 5**4 = 625 paths: def f():

Serhiy Storchaka added the comment: And there may be more than one return/break/continue statement in the try block. It increases the base of the degree. At least for "return" we perhaps can merge different cases. But it would complicate the compiler and cannot help in other cases.

[issue42872] Inconsistent exceptions thrown by pathlib.Path.mkdir on different OSes

Serhiy Storchaka added the comment: Yes, some operations can raise instances of different OSError subclasses on different platforms, because the corresponding C function sets different errno. It is so, and we cannot do anything with this. It is just a part of the difference between plaforms.
