Indeed.  But byte-compilation does execute macros and requires, so sometimes
it leads to such infinite recursions.

Ah, now that's more interesting: it's not an infinite recursion, it's only
a deep recursion.  Actually, it seems to be exceeding the default 600 by
just a tiny bit: it fails with 606 but succeeds with 607.

Indeed, it seems to be pushing it a tiny bit "too" far.
I'd suggest we bump the default to 1000.
