------- 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.
