Crash: address-of should not have intrinsic reference argument

[Thierry Delisle]

The code crashes the compiler due to an assertion:

CFA assertion error* "false" from program "cfa-cpp" in "Expression* GenPoly::{anonymous}::AddrRef::postmutate(AddressExpr*)" at line 302 in file "../../main/src/GenPoly/Lvalue.cc": AddrRef : address-of should not have intrinsic reference argument: Application of [...]

extern "C" {
	#include <sys/select.h>
}

int main() {
	fd_set fds;
	FD_ZERO(&fds);
	FD_SET(0, &fds);
}

typedef struct {

} fd_set;

int main() {
