The problem has been identified. It was due to storing the reference to a temporary variable which does not guarantee the validity of the variable value. This apparently only created a problem in CentOS 7, probably due to the specific compiler version that comes with that distribution.
Now a local copy of the temporary variable is made, so that it becomes non-temporary. The reference to this non-temporary variable is then stored.
