Subject: [PATCH] [Coverity] fix issue reported for SWIG_Python_FixMethods
Fix Coverity issue reported for SWIG_Python_FixMethods:
"buffer_size: Calling strncpy with a source string whose length
(10 chars) is greater than or equal to the size argument (10)
will fail to null-terminate buff."
The issue is only reported for the "swig_ptr: " line, but for
consistency we replace both occurrences of strncpy with memcpy.
