Bug#452811: gcc-4.2: [powerpc] ICE when using -funroll-loops

[Nacho Barrientos Arias <nacho@debian.org>]

Package: gcc-4.2
Version: 4.2.2-3
Severity: important

Hello,

gcc-4.2 (and others) dies building sks-ecc[0] on powerpc in the 
following situations.

   GCC Opt -funroll-loops Result
   4.1 O2  Yes            OK
   4.2 O2  Yes            ICE
   4.2 O1  Yes            ICE
   4.2 O0  Yes            OK
   4.2 O2  No             OK
   4.3 O2  Yes            ICE
   4.3 O2  No             OK

Gcc-4.3 is provided by gcc-snapshot 20070916-1, since 20071116-1 is not 
built for powerpc yet.

Some build logs, the preprocessed offending file (mpi.c) and package 
sources are available at http://people.debian.org/~nacho/debian/ice-ppc-sks/

Let me know if you need more debug.
