Internal compiler error on m68k for gcc-4.6
Hi all!
For me, it seems as if we have a toolchain problem, maybe caused by building the toolchain on emulated CPUs for a long term. But that's only a quick and simplified guess.
I experienced in Unstable some glibc double free problems, like when running schroot or apt-transport-https. So I tried to build gcc-4.6 myself and ran into an internal compiler error:

The bug is not reproducible, so it is likely a hardware or OS problem.

@Andreas: if you like to debug this... the machine in question is old elgar.debian.net and you seems to have had an account there. The build directory is still available.
The other thing I could do by myself is to reboot the machine and run some memory tests tomorrow...
