It's not valid, you can't pass a function type by value

--- Comment #5 from Richard Eames <naddiseo at gmail dot com> 2012-01-12 20:01:15 UTC ---
I've reduced the testcase further. It appears to be a problem with templates.
The reason I was passing a function type in the template was because
std::function<bool(Arg*)> wouldn't work for me. If I take out the first
parameter so that it's just the function pointer, then std::function works with
the lambda as a default argument, but as soon as the function is templated I
get the IRC.

Further reduced

function(T) { }
};
class Foo {
public:

void dostuff(function callback = []() { }) { }
};
int main() {
Foo foo;
foo.dostuff<int>();

This is fixed in mainline. I'm adding the reduced testcase and closing the
issue.
