[perl #41249] [BUG] [tru64] core dump in t/pmc/interp_3.pir

[Will Coleda via RT]

This ticket is against a very old version of parrot, and 
we can no longer duplicate it as we don't have access to this 
architecture.

If you can duplicate the error against a recent parrot on this 
machine, please open a new ticket at https://trac.parrot.org/.

Closing ticket.
