[Bug bootstrap/44768] arm-linux bootstrap broken on expmed.c:157:3: warning ICE

["ramana at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #4 from ramana at gcc dot gnu dot org  2010-07-02 16:15 -------
I'm getting this failure in stage3 thus just attaching the expmed.i
pre-processed file isn't enough to reproduce this with a cross. 

Doing a bisect I find that 

rev: 160827 - builds expmed.o in stage3 .
rev: 160833 - Segfaults while building expmed.o 

rev:160832 was this commit .

        * tree-sra.c: Include tree-inline.h.
        (create_abstract_origin): Removed.
        (modify_function): Version the call graph node instead of creating
        abstract origins and dealing with same_body aliases.
        * tree-sra.c (ipa_sra_preliminary_function_checks): Check whether the
        function is versionable.
        * Makefile.in (tree-sra.o): Add TREE_INLINE_H to dependencies.

        * testsuite/g++.dg/torture/pr43905.C: New test.

while 160833 touches only libstdc++



I think there is a case of memory corruption or miscompilation somewhere
because of which global_dc->printer changes value between 2 calls to
diagnostic_report_diagnostic. Still digging to find out what's gone wrong here
- might well be a latent bug exposed from elsewhere.
