Following standalone code will make the compiler (g++) loop:
void test()
{
__label__ 0;
}
command line: "g++ lbl.c". However "gcc lbl.c" works (with ONE error report)
!
output with g++ will be:
lbl.c:5: error: expected identifier before numeric constant
lbl.c:5: error: expected `,' before numeric constant
lbl.c:5: error: expected identifier before numeric constant
lbl.c:5: error: expected `,' before numeric constant
lbl.c:5: error: expected identifier before numeric constant
lbl.c:5: error: expected `,' before numeric constant
lbl.c:5: error: expected identifier before numeric constant
lbl.c:5: error: expected `,' before numeric constant
lbl.c:5: error: expected identifier before numeric constant
lbl.c:5: error: expected `,' before numeric constant
lbl.c:5: error: expected identifier before numeric constant

...
output with gcc:
gcc lbl.c
lbl.c: In function 'test':
lbl.c:5: error: parse error before numeric constant
