Subject: Fix for PR objc++/23614
This patch fixes PR objc++/23614.
It was not a bug in the ObjC++ compiler; it was a bug in the test.
The compiler barfed on:
class MyWidget {
public:
int a;
MyWidget(void) { a = 17; }
};
MyWidget *widget = nil;
and I think the compiler is correct in barfing, because widget is a pointer
to a C++ class, and you can't assign 'nil' to it. Note that this assignment
seems irrelevant in the test, which was testing something else.
Thanks
