I don't know about VC8 Pro but valgrind detects the memory leak at
line 95 of libormarketmodelprocess.cpp, the full output is below.
I haven't had time to investigate further but a first guess would be
that maybe the shared pointer to the LiborForwardModelProcess object
is used incorrectly such that the reference counting is circumvented
preventing the object from being deleted when the pointer goes out of
scope.
