Follow-up Comment #3, bug #56892 (project make):
I can think of one way to address these types of issues that might not be too
impactful:
Make knows both how deep inside a recursion it is (via MAKELEVEL) and also how
many times its re-exec'd itself (via MAKE_RESTARTS). It could check to see if
either of those values seems outrageous and stop. For example, if our
MAKELEVEL is > 100 or our MAKE_RESTARTS > 1000, or something, we'd fail with
an error.
I don't know if we'd need to provide a way for the user to reset these limits
in case they had a legitimate need for "outrageous" values.
