Hello!

As previously stated in [1], filing a new bug report for the gcc-4.8/4.9
bootstrap failure which was introduced recently. As Kaz already pointed out,
the failing reason is most certainly:

> gcc/d/ctfeexpr.dmd.o differs

Build logs:

gcc-4.8:
http://buildd.debian-ports.org/status/fetch.php?pkg=gcc-4.8&arch=sh4&ver=4.8.4-2&stamp=1432515052

gcc-4.9:
http://buildd.debian-ports.org/status/fetch.php?pkg=gcc-4.9&arch=sh4&ver=4.9.2-18&stamp=1432566734

Unfortunately, Matthias Klose doesn't split the patches in his SVN snapshots,
so I'm not sure how to properly bisect the problem. Any suggestions welcome.

The regression must have come through any of these changes [2].
