I'll take a look at it, thanks for letting me know

[jonringer]

This is an upstream issue Gallopsled/pwntools#1189, reverting pyelftools to 0.24 does in fact fix it.

Seeing as this has been an issue for a year, not sure how quickly they will fix it

[kristoff3r]

I'm actively working with the maintainers to get a new release out (the current defacto maintainers didn't have access to do the releases). When that happens the fix should be a simple version bump.
