>Description:
Looks like in some cases rcorder releases the same memory several times. Of course tests below are quite unusuall for standard rc.d content and explicitely include invalid entries with circular dependency but anyway..

>How-To-Repeat:
$ ls -l

-rwxr-xr-x  1 ianzag  wheel  65 Mar  9 17:38 first
-rwxr-xr-x  1 ianzag  wheel  64 Mar  9 17:39 second

$ cat first

# PROVIDE: first
# REQUIRE: second
# BEFORE: second

$ cat second
