Test program:
template <class T> class foo
{
public:
static const unsigned long long max = (T)~0ULL;
bool toobig (unsigned long long val)
{
return val > max;
}
};
Message:
test.cc: In member function ‘bool foo<T>::toobig(long long unsigned int)’:
test.cc:7: error: ‘T’ used where a ‘long long unsigned int’ was expected
The baffling part is that T doesn't occur anywhere in or near line 7. It's
almost as if the initialization part of the static const member has been
textually substituted in line 7 -- but if it were that should still be legal...
It works ok if I explicitly initialize the member outside the class definition
via specializations, which is tolerable given that only a small number of cases
of this template class are used.
