Compile with pedantic-errors, C99 or C90.
extern int x;
#if 1 ? 0: 1 ? 1/0: 1/0
#endif
Code is fine as the divisions by zero are unevaluated.

------- Comment #1 from tromey at gcc dot gnu dot org 2008-04-30 17:51 -------
Confirmed.
The bug is that we look at top[-1].value after overwriting it with the
value of the 'true' branch of the condition.
