2nd code block

As code, when g_useNewStackAlloc is set, size of "old" array' is returned.
The name of flag is not matched with its usage. I guess NOT operator (!) is missing like below:

template <class ELEMENT>
size_t StackVector<ELEMENT>::size() const
{
if (!g_useNewStackAlloc)
return m_oldArray.size();
else
return m_newArray.size();
}

1st paragraph

"then isExplicitContext won’t
be set, and reserve will run exactly as before." should be
"then m_isExplicitContext won’t
be set, and reserve will run exactly as before."

In the code, there is no variable which name is "isExplicitContext".
