[Tinycc-devel] MAJOR bug: tcc doesn't detect duplicate cases in switch statements

[arnold]

Hi All.

On the latest mob:

$ cat foo.c
int main(int argc, char**argv)
{
        int a;

        switch (a) {
        case 1:
        case 2:
                break;
        case 3:
                break;
        case 1:
                break;
        default:
                break;
        }

        return 0;
}
$ PATH=/tmp/tcc/bin:$PATH tcc foo.c
$

$ gcc foo.c -o foo
foo.c: In function ‘main’:
foo.c:11:2: error: duplicate case value
  case 1:
  ^
foo.c:6:2: error: previously used here
  case 1:
  ^

This is pretty serious....

Thanks,

Arnold
