--- Comment #5 from jevgenijsz1 at verifone dot com --- Moreover if I was to put a breakpoint in struct hash<EnumType> I can see that it is being used 4 times in the code example posted: twice to hash the EnumType on insertion and twice on access (however the second access attempt throws an exception)
