I would first assume an error in this project -- and not in g++-4.5 :-)

However, before writing a bug, it would be very usefull if you succeed
to reduce the test case: I'm almost sure that none of the g++-developers
will be happy with a bug report stating "somehow those 1000's lines of
code don't compile correctly" -- I would expect a much faster help if
you could reduce the problem and reduce it to a few hundred (or even a
few tenth) of lines of code...
Is that possible?

I just had a VERY quick look at the code: It seems that "mutrec" is
defined in "aa.cpp". Do you link aa.cpp and grafrs.cpp together?
