Probably not, I used -j8.

Well, gcc is now written in C++ and 4.2.2 might have quite a few bugs
in this regard so I would not completely rule it out.

Well, if you can't reproduce it there then the bug was fixed :-)

I suggest that you try to replicate my steps outlined in comment #5
first.  If you can't reproduce the error that way, then we need to
look at differences in how I and you build stuff.  If it still fails,
then I would suggest trying a fresh checkout from the git branch and
finally trying a newer host compiler.
