[v4] malloc: fix memleak in function muntrace
Commit Message
when we call functons as follow:
setenv("MALLOC_TRACE", "/tmp/mtrace.log", 0);
mtrace();
...
muntrace();
It would cause memleak, for the mtrace malloc some memory:
mtd = malloc(TRACE_BUFFER_SIZE);
and it would not be free. Therefore it should be freed in muntrace.
