It would either appear that this isn't a duplicate or the bug specified as
duplicate has not been fixed even though it is marked as fixed.  I do not see
any trace of the patches specified in bug-15868 and this reported problem has
not been fixed, so perhaps it hasn't been committed yet.  There are some
differences, though.

bug-15868 is for an hppa-linux target and fails in expand_expr_real_1, at
expr.c:6634

This bug fails in change_address_1, at emit-rtl.c:1811

Are you sure that this patch did not fix it:
        * gimple-low.c (struct lower_data): Replace the_return_label and
        one_return_stmt with return_statements.
        (lower_function_body): Process the entire list of return_statements.
        (lower_return_expr): Check source value before unifying return_exprs.
        * gimplify.c (gimplify_return_expr): Force the use of a temporary
        for !aggregate_value_p.
        * tree-gimple.c: Update RETURN_EXPR grammer.

As it did fix the other bug for sure as there is testresults from it today: <http://gcc.gnu.org/ml/gcc-
testresults/2004-06/msg00323.html>.

Also if it is not fixed can you attach the preproccessed source?

preprocessed sources

This is what the stage1 compiler was working on when it failed.

I just confirmed that the patches are listed in the Changelog for gcc and it
still fails with the same backtrace supplied previously.

Just got a bunch of changes from cvs.  The only thing I can think of is my brain
pattern recognition is faulty when looking at the Changelog or I managed to get
a cvs up where the Changelog entry was done but not the actual source changes.

Anyway, Andrew's previous assignment as a duplicate was correct and it is indeed
fixed.  Currently building and made it to stage2.
