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).
No, actually, it's not.
It's caused by one of Jan's patches to remove unreferenced vars.
In fact, i'm pretty sure he already fixed this bug.
