ForkingPickler Issue

[gilboz]

Description

Running on python 3.13.1 (MacOS Apple Silicon)

Seems like the SpecialMem class that is defined in rop_utils.py:make_initial_state causes the call to find_gadgets() fail.

The root cause is that the multiprocessing Pool uses ForkingPickler (pickle) which cannot serialize non top-level classes.

Suggested resolution:
Move SpecialMem class definition to the global scope, this solved the issue for me.

Thanks for bringing this up. This seems to have been fixed in our private branch but not the public one. Since the private branch will be merged soon (tm), I'll just leave it as is for now.
But yeah, I'll leave this issue open before the merge actually happens.

This issue should be fixed now that the private branch is merged: #136
