[Bug tree-optimization/27826] New: ICE in copy_to_mode_reg

["sander at mi dot fu-berlin dot de" <gcc-bugzilla at gcc dot gnu dot org>]

I am getting an ICE when compiling a c++ source with optimization turned one.
My compiler version is

sander@haile:~/tmp$ g++-4.1 -v
Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v
--enable-languages=c,c++,java,fortran,objc,obj-c++,ada,treelang --prefix=/usr
--enable-shared --with-system-zlib --libexecdir=/usr/lib
--without-included-gettext --enable-threads=posix --enable-nls
--program-suffix=-4.1 --enable-__cxa_atexit --enable-clocale=gnu
--enable-libstdcxx-debug --enable-java-awt=gtk --enable-gtk-cairo
--with-java-home=/usr/lib/jvm/java-1.4.2-gcj-4.1-1.4.2.0/jre --enable-mpfr
--with-tune=i686 --enable-checking=release i486-linux-gnu
Thread model: posix
gcc version 4.1.1 20060511 (prerelease) (Debian 4.1.0-4)

The command line that triggers the bug is

g++-4.1 -c grid.i -O

The output produces is

grid.i: In member function 'int Dune::ALU3dGrid<dim, dimworld,
elType>::size(int, int) const [with int dim = 3, int dimworld = 3,
Dune::ALU3dGridElementType elType = tetra]':
grid.i:52998: internal compiler error: in copy_to_mode_reg, at explow.c:577
Please submit a full bug report,

When compiled without the -O the ICE does not occur.
