This one of the six tests, but I do not see the names of the other five.
Until I know what they are and can look at their code, I can't tell whether
a global disabling of this flag is better than either (a) disabling -Winfinite-recursion
just for these test cases, or even (b) rewriting the test cases to avoid triggering
this flag. I think (b) is definitely the way to go for higher_order5.m.
