| I had similar fails to Nathan on 3.4.  See
| <http://gcc.gnu.org/ml/gcc-testresults/2003-02/msg01389.html>
| and <http://gcc.gnu.org/ml/gcc-testresults/2003-02/msg01429.html>.

| There is also a new fail for static9.C on both 3.3 and trunk.
| See <http://gcc.gnu.org/ml/gcc-patches/2003-02/msg02340.html>.

Within that window, there is also this patch of Mark's

  2003-02-25  Mark Mitchell  <mark at codesourcery dot com>

        PR c++/9683
        * decl2.c (prune_vars_needing_no_initialization): Do not throw
        away initializations for DECL_EXTERNAL VAR_DECLs.
        (finish_file): Adjust accordingly.
        * pt.c (instantiate_decl): Do not defer VAR_DECLs.


And given the nature of the errors on mainline:

/home/gcc/src/egcs/gcc/testsuite/g++.dg/other/error2.C:13: error: declaration of `operator>>' as non-function
/home/gcc/src/egcs/gcc/testsuite/g++.dg/other/error2.C:13: internal compiler error: Segmentation fault

[...]

and given that my patach does not cause regression on branch, I'm
suspecting Mark's.

Still investigating.
