[Bug c/21873] [3.4/4.0/4.1 Regression] infinite warning loop on bad array initializer

[jsm28 at gcc dot gnu dot org]

------- Additional Comments From jsm28 at gcc dot gnu dot org  2005-06-03 23:30 -------
Confirmed.  There are lots of related cases which yield infinite loops (with or
without diagnostics).  All versions 3.0.x onwards either loop or ICE on some
such tests; 2.95.3 avoids both (although it doesn't diagnose them all either). 
Testing a patch for mainline and 4.0 branch (probably safe for 3.4 branch as well).
