I think there is a dup of this bug without auto. Not to mention it was defect report against the standard.

The following code:

template <typename T> void foo();
void f() {auto g = foo<int>;}

fails to compile in GCC 4.5.0's C++0x mode with the following error:

foo.cpp: In function ‘void f()’:
foo.cpp:2:20: error: ‘g’ has incomplete type

Trying different variants of this code, it appears that GCC believes that foo<int> is an ambiguous overloaded function, while there is only one matching
