>Organization:
>Environment:
i686-pc-linux-gnu
Thread model: posix
>Description:
gcc aborts with segfault after a parse error. Seems new since gcc-3.3:
output:
$ gcc x.c
x.c: In function `main':
x.c:5: error: parse error before "case"
x.c:3: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

>How-To-Repeat:
x.c:
int main () {
  switch (3)
    case 3:
      1, /* note comma! */
    case 4:
      2;
}
>Fix:
always write correct c-programs! This is better anyway.
