If you think of PR46915: I was the one that originally stumbled over this 
although GM took the hard work of bisecting and reporting that upstream. As I 
said before, the compiler is 4.5.2.

And: no, I don't suspect a compiler error. Only a .config screwup. I'm 
currently trying to find the culprit. Good luck it breaks rather early in the 
compile.

To reproduce try to compile for hppa64 with default .config, this seems what 
has happened to me.
