getcwd(NULL, size) returned memory from the guest heap directly, while
the caller frees it with free(), which goes to the application heap.
With a title's malloc replacement registered, that free reached the
replacement with a pointer it never returned. Allocate from the
application heap like strdup, and report ENOMEM when it returns null.
