Synopsis: gcc-3.4 segfaults on false case label

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Fri Jan 10 09:09:37 2003
State-Changed-Why:
    Confirmed. The code crashes 3.3 and 3.4, but not 3.2 and 
    previous versions.
    
    My compiler collection tells me that the ICE is displayed
    since a change between 2002-01-15 and 2002-02-01. However,
    before that I get "confused by previous errors...", a
    behavior that started between 2001-02-01 and 2001-02-15.
    Before that I see the ICE again, so this information is
    probably not of great help in this case...

>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.

>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.
