The bug has been fixed in gcc (though it may not have hit 3.4 CVS yet). See debian #307993 for details. This bug was causing any arch to die when building glibc with -g1, it's a gcc 3.4 regression, and now that it's fixed, it should be possible to switch the 2.3.5 package to gcc 3.4 (well, at least as soon as the fix hits debian's gcc 3.4 package) Ben.
