  I wouldn't think so.  I would guess this is an utterly bogus bit of code in
Perl, the equivalent of returning the address-of a stack auto variable when
you return from the function in whose scope it's allocated, and needs tracking
down in the upstream sources.  It should unlink its exception registration
before it returns.

    cheers,
