Once again, I know nothing of working with IPC, and thus was curious...dug around a bit on CPAN
and noticed that IPC::Run3 seems to be reasonably current
and has only a couple of bugs with recent activity dating around March this year.

Again, this might not even be appropriate or applicable, but thought that the patch idea might work (or be more hopeful)
if you tried it with a more recent package.

At the bottom of the CPAN link above there seems to be a comparison to IPC::Run, though I don't know how objective that might be.

At any rate, hope this is worth considering(aka reasonably helpful) for you.
