The memset() just forces the bug to the surface in builds where the ckmalloc()/ckfree() routines of TCL are using caching that prevents valgrind/ASAN from seeing the use-after-free. The memset() is not part of the bug fixx itself, but is a preventative measure to try to prevent similar bugs in the future. -- D.
