[svn:parrot] r35855 - trunk/src

New Revision: 35855

Modified:
   trunk/src/sub.c

Log:
[GC] Worked around a spurious segfault-inducing problem in the GC where STRINGs
sometimes get the "Hey, I'm a PMC!" flag set.  Somehow r35847 didn't quite do
the trick.  This does.  Whiteknight and I will track this down -- but no time
before the release.
