Steps to Reproduce:
$ cat foo.c
int
foo(void)
{
   if (sizeof(long) == 8) {
      typedef union {
         long i;
         char c[8];
      } comm;
      comm static volatile u;
      u.i = 0x01020304;
      u.i <<= 16, u.i <<= 16;
      u.i |= 0x05060708;
      return u.c[0] == 0x01 && u.c[1] == 0x02;
   }
   return 2;
}
$ gcc -O0 -g -c foo.c

foo.c:16: internal compiler error: in dwarf2out_finish, at dwarf2out.c:14116
Please submit a full bug report,
with preprocessed source if appropriate.

Additional info:
By omit "-g" or change "-O0" to "-O1", we can get around this error.

Comment 1 KISHIMOTO, Makoto 2006-03-30 23:19:53 UTC
The code is minimal fragment to reproduce the problem in SpiderMonkey.
(
http://bonsai.mozilla.org/cvsblame.cgi?file=mozilla/js/src/jscpucfg.c&rev=3.25#255 )
When compile this, with options "-O0 -g -c", cause the error.
