Hello.
First, I'm new in gcc.
I'm moving our project on gcc and I meet this bug.
My code:
template <typename T, bool F>
struct sp
{
sp ()
{
}
};
struct X
{
typedef sp <X, true> sp_x;
//X (sp_x x = sp_x ()) // OK
//X (sp <X, true> x = (sp <X, true> ())) // OK
X (sp <X, true> x = sp <X, true> ()) // ERROR
{
}
};
My gcc output:
g++ -o /home/zerg/bs/plugins/test.o -c -v -save-temps
/home/zerg/bs/plugins/test.cpp
Using built-in specs.

I read all comments and saw a patch. But I don't know how I can fix my gcc with
this patch.
