Hi!
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. I'm working to get a small reproducer.
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
