[Bug tree-optimization/42703] [4.5 Regression] ICE in generate_subtree_copies with out of bounds array access

["pinskia at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #4 from pinskia at gcc dot gnu dot org  2010-01-12 20:48 -------
This code is undefined because out of bounds access of the array.  Also note
the use of the union is not needed here really as char is a character type
which means it can be used to access the ScmUInt64 without any aliasing issues.
