[Bug tree-optimization/38405] [4.4 Regression] (silent failure) handling bitfield in ternary

[rguenth at gcc dot gnu dot org]

------- Comment #5 from rguenth at gcc dot gnu dot org  2008-12-05 11:23 -------
The error is likely

Folding statement: D.1241_5 = D.1242_4 != 0;
Folded into: D.1241_5 = (int) D.1242_4;

which is wrong for

  <unnamed-signed:1> D.1242;

because it sign-extends.
