--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Clang also compiles it, and prints "1".
EDG rejects it as ambiguous:
"a.cc", line 8: error: more than one instance of overloaded function "foo"
matches the argument list:
function template "int foo<T>(int)"
function template "int foo<T>(int)"
argument types are: (int)
return foo<int>(0);
^
1 error detected in the compilation of "a.cc".
