[perl #132316] [SEGV] Crash while running program (MongoDB module)

[Aleks-Daniel Jakimenko-Aleksejev via RT]

FWIW, when toasting I observed double free or corruption when installing both
BSON and MongoDB modules. The issue is really there, and should be reproducible
by just running the tests. That said, I've been running BSON tests locally in a
loop for hours with no luck.
