In general, sure, but given this particular failure, it seems to me
that it would occur somewhere if and only if it occurs everywhere?
It's a long-only doctest verifying that this line of code
raise AlarmInterrupt(msg)
raises an appropriate error. The difference between the given output
and what is actually produced is
AlarmInterrupt
versus
AlarmInterrupt: FLINT exception
So it could be that msg is "" on some platforms by "FLINT exception"
on others? It seems unlikely.

Here's the snip. It involves code you re-wrote (the sig_str stuff).
