New Revision: 41783
URL: https://trac.parrot.org/parrot/changeset/41783

Log:
[pcc] Initialized the PMC return value in run_sub() to PMCNULL explicitly.
This way, when PCC doesn't set a return value in those cases where the invoked
sub doesn't have a return value, the return value will be PMCNULL, not whatever
random junk is on the stack that is almost assuredly not a -- and is definitely
not the -- valid PMC.
