[Bug c/16925] New: ICC when building a m68hc11 cross-compiler on 64-bit architectures

["aurelien at aurel32 dot net" <gcc-bugzilla at gcc dot gnu dot org>]

I am unable to build a m68hc11 cross-compiler on 64-bit architectures. xgcc
generates an internal compiler error during the build of libgcc2:

The problem is _not_ present in gcc 3.2.3, but present in gcc 3.3.1, gcc 3.3.2,
gcc 3.4.0 and gcc 3.4.1

The problem seems to be present only on 64-bit architectures (alpha, amd64 and
ia64), and in all cases, the problem occurs on the same file, same line, with
the same error message.

configure line used:
./configure --prefix=/home/aurel32 --with-gnu-as --with-gnu-ld --enable-nls
--without-included-gettext --disable-checking --enable-languages=c,c++
