 FYI, i tried the same test with some older versions of GCC, slightly
 modified from stock sources as well (same mods as in the 3.2.1
 mentioned above, which shouldn't affect this), and
 
 * "gcc version 3.0.3 with SiByte modifications" worked fine.
   (same for 3.0.4)
 
 * "gcc version 3.1.1 with SiByte modifications" also crashed.
 
 So, this seems to be a regression from previous releases (at least
 3.0.x).
 
 I'm can provide the diffs against unmodified gcc from any of those
 "with SiByte modifications" versions to the sources, if people want
 them, but really, they're not the problem.  8-)
