Subject: Filter::exec perl 5.20.1 bad free() on __DATA__

With my build of Filter 1.54 and recent debian i386 perl 5.20.1, echo __DATA__ | perl -MFilter::exec=cat - gets *** Error in `perl': free(): invalid pointer: 0x095571f9 *** Aborted where I hoped it would do nothing, which is what you get from echo __DATA__ | perl - I don't know if Filter::exec or perl is to blame, or if filters don't work at all with __DATA__. If it can't work then it'd be good to give some error rather than a bad free(). In 5.20.0 I think the same thing segfaulted instead of free(), but I don't have that to try any more.
