[Autocrasher]

2 new FAIL's (22 total) have appeared for i686-pc-linux-gnu:
    g++.sum g++.old-deja/g++.other/unchanging1.C
    gcc.sum gcc.misc-tests/gcov-4.c
These tests passed the last time they were ran.

Attached are the ChangeLogs since the previous run.  Possibly a patch with
your name on it has caused the problem(s).
