Hi

With latest svn I get segmentation fault while booting the testimage arm-test-0.2.tar.gz:

qemu-system-arm -kernel zImage.integrator -initrd arm_root.img -nographic -append "console=ttyAMA0"
Uncompressing Linux................Segmentation fault

Reverting to svn version 4137 (just before the arm convertion to TCG)
everything works fine.

I am building with gcc-3.4 (GCC) 3.4.6 (Debian 3.4.6-7)

Attached is a full backtrace.

Regards
Lars Munch
