Sure, that was deliberate.

And indeed, that is what was done - otherwise the tests in the current
sources would not pass. But they do. I would of course have run (and
updated) them when fixing the bug. A grep for 'number too big' in
testdata2 shows this:

Failed: number too big in {} quantifier at offset 7
Failed: number too big in {} quantifier at offset 8
Failed: number too big in {} quantifier at offset 9
Failed: number too big in {} quantifier at offset 11

So... the problem is perhaps that a patch was applied to the code and
not to the test data?
