[Bug tree-optimization/30631] New: Trunk GCC fails to compile cpu2k6/dealII at -O2

["grigory_zagorodnev at linux dot intel dot com" <gcc-bugzilla at gcc dot gnu dot org>]

GCC 4.3 compiler revision 121206 gets ICE while compiling cpu2006/447.dealII
source file data_out_base.cc at -O2 optimization level on x86_64-redhat-linux.

Similar to previously reported cpu2k6/perlbench failure, this regression is
caused by "Rewrite of portions of points-to solver" patch
http://gcc.gnu.org/ml/gcc-patches/2007-01/msg01541.html (revision 120931).

Error log is listed below. 

data_out_base.cc: In static member function 'static void
DataOutBase::write_vtk(const std::vector<DataOutBase::Patch<dim, spacedim>,
std::allocator<DataOutBase::Patch<dim, spacedim> > >&, const
std::vector<std::basic_string<char, std::char_traits<char>,
std::allocator<char> >, std::allocator<std::basic_string<char,
std::char_traits<char>, std::allocator<char> > > >&, const
DataOutBase::VtkFlags&, std::ostream&) [with int dim = 3, int spacedim = 4]':
data_out_base.cc:2949: internal compiler error: tree check: expected tree that
contains 'decl minimal' structure, have 'reduc_max_expr'  in
