[Bug c++/32718] New: g++ looping on bad __label__ declaration

[tony at rogvall dot se]

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
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
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
