patch 9.0.0013: reproducing memory access errors can be difficult

Browse Source 
Problem:    Reproducing memory access errors can be difficult.
Solution:   When testing, copy each line to allocated memory, so that valgrind
            can detect accessing memory before and/or after it.  Fix uncovered
            problems.
