Description Scott S 2010-03-16 04:17:47 UTC 
Unable to build the kernel when attempting to downgrade from ~amd64 (gentoo-sources-2.6.33) to amd64
Using gcc-4.4.3 (x86_64-pc-linux-gnu-4.4.3)

Final snippet of make output in /usr/src/linux:

  CC      arch/x86/kernel/trampoline.o

After a make clean, same thing happens


Reproducible: Always

Seems fine with gcc-4.3.4, no hurry to fix
