[cfe-dev] Address of compound literal (-std=gnu++0x)

[Allan Odgaard]

The code below is C99 and supported by GCC in C++ mode since they allow 
C99 features.

Clang accepts the code in C99 mode, it (correctly) says that compound 
literals are a C99-specific feature in C++ mode, but with -std=gnu++0x 
(which should support GCC extensions, i.e. C99) I get the following 
error:

     error: taking the address of a temporary object of type 'struct 
point' [-Waddress-of-temporary]

----------8<----------

struct point { int x; int y; };
void draw_point (struct point const* aPoint) { }

int main (int argc, char const* argv[])
{
	draw_point(&(struct point){ 1, 2 });
	return 0;
}
