The following code generates two different, ambiguous declarations of foo. I
guess this is regression, as other compilers accept the code.
I am using gcc 4-3-3
template<class A,template<class>class B> void foo(B<A>)
{
}
template<class> class bar
{
template<class A,template<class>class B> friend void foo(B<A>);
};
int main(int num_arguments, char* arguments[])
{
foo(bar<int>());
/*error: call of overloaded 'foo(bar<int>)' is ambiguous
n:298: note: candidates are: void foo(B<A>) [with A = int, B = bar]
n:303: note: void foo(B<A>) [with A = int, B = bar,
<template-parameter-1-1> = int]*/
}
