>Description:
struct HwQueue
{
void pop ();
};
struct ISPmq : HwQueue
{
};
struct ISImq : HwQueue
{
};
struct IS : ISPmq, ISImq
{
void monk ();
};
void IS::monk()
{
ISPmq::pop();
}
$ gcc-3.0 -c -pedantic twosamebase.cpp
twosamebase.cpp: In member function `void IS::monk()':
twosamebase.cpp:21: `HwQueue' is an ambiguous base of `IS'
Without -pedantic there is not even a warning (even with -W -Wall).
10.2.1 says "for a qualified-id, name lookup begins in the scope of the nested-name-specifier". In which scope, I don't think the reference to pop() or HWQueue, for that matter, is ambiguous.
>How-To-Repeat:
>Fix:
Workaround: this->ISPmq::pop(); works fine.
