+ modify update_getenv() in db_iterator.c to ensure that environment variables which are not initially set will be checked later if an application happens to set them (patch by Guillaume Maudoux). + remove initialization-check for calling napms() in the term-driver configuration; none is needed. + add help-screen to test/test_getstr.c and test/test_get_wstr.c + improve compatibility between different configurations of new_prescr, fixing a case with threaded code and term-driver where c++/demo did not work (cf: 20160213). + the fixes for Redhat #1464685 obscured a problem subsequently reported in Redhat #1464687; the given test-case was no longer reproducible. Testing without the fixes for the earlier reports showed a problem with buffer overflow in dump_entry.c, which is addressed by reducing the use of a fixed-size buffer. + add/improve checks in tic's parser to address invalid input (Redhat #1464684, #1464685, #1464686, #1464691). + alloc_entry.c, add a check for a null-pointer. + parse_entry.c, add several checks for valid pointers as well as one check to ensure that a single character on a line is not treated as the 2-character termcap short-name. + fix a memory leak in delscreen() (report by Bai Junq). + improve tracemunch, showing thread identifiers as names. + fix a use-after-free in NCursesMenu::~NCursesMenu() + further amend incorrect calls for memory-leaks from 20170617 changes (report by Allen Hewes).
