[Bug bootstrap/44959] New: [4.5 Regression] bootstrap failed at Comparing stages 2 and 3

The problem was first noticed with 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40894#c4 with svn-r152154 .

Now that 4.5.0 is released, here is the build failure - it looks the same as in
the url above, and earlier than bug 40894 so this I guess qualifies as a new
bug.
