13186	Memory leak in serialization 1.65	anonymous	Robert Ramey	"Hi, we are seeing a seg fault seemingly caused by a difference between boost serialization 1.64 and 1.65 (no problems in 1.64 or any other boost we are currently testing >1.48 as part of Chaste computational physiology library). Unfortunately the minimal failing test is a bit complicated I'm afraid, this only seems to show up with a hierarchy of serialization classes.

I've attached valgrind memory testing output which should hopefully give all the clues needed to track it down:

Incidentally, the consequences are exactly the same as a problem that existed in boost 1.46 and was fixed in 1.48. I don't know if the underlying problem is related."	Bugs	new	Boost 1.65.0	serialization	Boost 1.65.0	Showstopper
