Ansible ssh errors with script module on OpenSSH 6.6.1

Hello,

TL;DR: recently upgraded OSes. script module no longer functions. May be due to new openssh version. Script runs correctly and ansible module doesn’t seem to throw an error, so it looks like some kind of false positive when parsing ssh stderr stream.

FWIW, the ansible machine is scientific linux 7.1 and the host is scientific linux 6.6.

sl 7.1 output (openssh 6.6.1)
