      } 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;

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.
