Bug#361560: FTBFS with GCC 4.2: llvm's xgcc: Internal error: Illegal instruction
Package: llvm
Version: 1.6-1
Your package fails to build with GCC 4.2. Version 4.2 has not been
released yet but I'm building with a snapshot in order to find errors
and give people an advance warning. I'm not sure if the bug below
indicates a bug in your package or in GCC - presumably the latter but
I've no idea how to find out. Maybe you can investigate. You can
reproduce this with the gcc-snapshot package.
