[Bug middle-end/40692] [4.5 Regression] Endless recursion between fold_ternary and fold_cond_expr_with_comparison

[jakub at gcc dot gnu dot org]

------- Comment #1 from jakub at gcc dot gnu dot org  2009-07-08 23:09 -------
Caused by r149060.  Will debug tomorrow.
Alternative testcase that doesn't warn about VLA at file scope:
#define M1(x) (((x) & 0x00000002) ? 0x2 : ((x) & 0x1))
#define M2(x) (((x) & 0x0000000c) ? M1 ((x) >> 2) << 2 : M1 (x))
struct A { char f[1]; };
int foo (void)
{
  return M2 (4096UL - (long)&((struct A *) 16UL)->f);
}
