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 add_call_clobber_ops, at tree-ssa-operands.c:1780 Please submit a full bug report, with preprocessed source if appropriate.
