--- Comment #2 from Jan Beich (mail not working) <jbeich@FreeBSD.org> ---
Comment on attachment 179660
  --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D179660
The patch use a explicit cast (void *) and a more specific value -1

> -				if (pipeLeafs < 0)
> +				if (pipeLeafs =3D=3D (void *)-1)

popen(3) unlike pipe(2) returns NULL on failure, not (void *)-1.

> -				if (outputLeafs < 0)
> +				if (outputLeafs =3D=3D (void *)-1)

Ditto for fopen(3) unlike open(2).
