>Description:
try to compile this code:
=== Cut ===
class fooObject {};
typedef void (fooObject::*Func)();
class foobar : public fooObject {
void add(Func fncHandler);
void somefunc();
void init() { add(static_cast<Func>(&(foobar::somefunc))); }
};
=== Cut ===
The code might look a bit stupid, its a minimum testcase. the actual code
is different.
command line:
#g++ -c foobar.cpp
error message:
invalid static_cast from type `<unknown type>' to type `void (fooObject::*)()'
Code compiles fine with any previous gcc/egcs release. Is broken
with gcc CVS for quite a while already.
>How-To-Repeat:

unknown. urgently needed.
