Binary package hint: gcc-4.3

Compiling schroot on armel gives an ICE when compiling sbuild-chroot-config.cc with either -O2 or -O1. Compiling it with -O0 does not cause an ICE.

Building it with gcc-4.2 does not produce an ICE, either. schroot is unbuildable with gcc-snapshot since schroot requires boost, and gcc-snapshot does not like the headers boost provides.

Here is the full command line, with warnings and crash:
