Bug#233633: gcc-3.3: recent ICE regression in 3.3 while building xfree86
Package: gcc-3.3
Version: 3.3.3-1
Severity: serious
This must be a recent regression as either Phil Blundell or Othmar
Pasteka built earlier versions of xfree86 when they were in
experimental without problems.
I've made the preprocessed source available here:
http://people.debian.org/~troup/misc/util.i.gz
Compiling without optimization makes the ICE disappear (though that's
hardly surprising). In addition to working with previous gcc-3.3
packages, it also works with gcc-2.95 and gcc-3.2. It fails in the
same way with the most recent gcc-snapshot package (20040118).
