           Summary: no conversion of build-in binary operator argument
                    attempted
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: d dot frey at gmx dot de
                CC: gcc-bugs at gcc dot gnu dot org

Consider the following code snippet:

struct A {
    template< typename T > operator T() const;
} a;

template<> A::operator float() const
{
    return 1.0f;
}

int main()
{
    float f = 1.0f * a;
}

The GCC 3.3 says:

t.cc: In function `int main()':
t.cc:12: error: no match for `float * A&' operator
t.cc:12: warning: unused variable `float f'

which is probably incorrect. EDG-based compilers like the code and 5.6/2 and 5/9
suggest that they are right. The GCC seems to be unable to decide which
conversion is appopriate and thus fails to attempt to cast A to float. This is
in the GCC since (at least) 2.95.3.

Regards, Daniel
