Inconsistency with ungreedy unset backrefs #349

Closed addisoncrump closed 11 months ago

addisoncrump commented 12 months ago

I cannot find a version for which the behaviour is consistent, so I assume this bug has been around since the JIT compiler.

In this case I believe the JIT is wrong, as ungreedy here should just be 1 match of empty.

@zherczeg , this is another one where I think the interpreter's behaviour is the right one.
