pass pOrigPath (strdup'd) to dirname(3) instead of pPath to avoid double free

from the dirname(3) manual:
Both dirname() and basename() may modify the contents of path, so copies
should be passed to these functions.
Furthermore, dirname() and basename() may return pointers to statically
allocated memory which may be overwritten by subsequent calls.
