    My assumption here is that you initially created this patch for 11, 12, or 13, and then backported to 1.8. This line doesn't fit in 1.8 because recording_fs does not exist there. The problem is, I don't know where in the 11+ code this ast_closestream() call is supposed to be.

> Fix cleanup in __ast_play_and_record where others[x] may be leaked.  This was caught where prepend != NULL && outmsg != NULL, once realfile[x] == NULL any further others[x] would be leaked.  I also added a cleanup block for prepend != NULL && outmsg == NULL.
