[Bug optimization/13266] New: ICE in tree-dfa.c for C++ source code

["schnetter at aei dot mpg dot de" <gcc-bugzilla at gcc dot gnu dot org>]

I use the tree-ssa gcc version from December 1st: 
 
$ ~/gcc-3.5-tree-ssa/bin/g++ --version 
g++ (GCC) 3.5-tree-ssa 20031201 (merged 20031130) 
 
 
 
I compile with optimisation with the options 
 
/home/eschnett/gcc-3.5-tree-ssa/bin/g++ -DCARPET_INT -DCARPET_REAL 
-DCARPET_COMPLEX -march=pentium3 -malign-double -m128bit-long-double -g -O3 
-funroll-loops -Wall -Wpointer-arith -Wcast-qual -Wcast-align -c -o /home/

and receive the error message
