I don't think there's anything wrong with that implementation of for_each
(). What "pre-increment" are you talking about? I see a for loop with no
for-init-statement, a valid condition, and an expression that increments
__first. There no different between:
for ( ; __first != __last; ++__first)
__f(*__first);
and
for ( ; __first != __last; __first++)
__f(*__first);
except that using pre-increment is more efficient when an iterator is not a
pointer.

I don't understand why the code is in a function beginning with "demangle".
Is the some weird issue with the debugger? Put a breakpoint in the
destructor of XPathFunctionTable and make sure it's not being entered a
second time.
I've built and tested the latest code on both xlC 3.6.6 and xlC 5.02 and
had no problems, so something must be going on in your code.

Hi,
for_each(m_FunctionCollection.begin(),
m_FunctionCollection.end(),
DeleteFunctorType());
The above call should be for deleting the vector of Function
pointers(vector<Function*>).
But if you see for_each function
----------------
template <class _InputIter, class _Function>
_Function for_each(_InputIter __first, _InputIter __last, _Function __f) {
for ( ; __first != __last; ++__first)
__f(*__first);
return __f;
}
------------
It is pre-incrementing Function pointer. So first one will not be deleted.
To my knowledge it looks like a leak.
Here is the core. I am not sure, if the below core is related to the above
problem.
Type 'help' for help.
