OTOH, if a repro is impossible maybe you could help debug this?
[since you're hacking the code already]
E.g., for the frame problem, is it possible to set a breakpoint on one of the
frame functions early on, when f_smob->inferior is not NULL, set a watchpoint
on it, and then continue? When the watchpoint triggers a backtrace may be
sufficient to isolate the culprit.
