Presumably the previous version 2.4 was working fine, so its something
introduced between then and 2.4.90 that causes the breakage. Since you
have a trivial reproducable test case, probably the easiest thing is to
take upstream git and run a bisect across it with your test case.
Very good point - I'll bisect it now.
