SSH crash on OpenBSD (pledge related?)

I just ran upon this problem and couldn't find it in bugzilla.
SSH crashes (abort trap) if all of the following conditions are met:
(a) option -f is used (crash happens when going to background),
(b) reverse port forwarding is set up (option -R),
(c) option ExitOnForwardFailure is enabled,
(d) there are no actual port-forwarding failures.
The problem can be reproduced by running this command:
ssh -f -N -R 1234:[::1]:4321 -o ExitOnForwardFailure=yes ::1
Repeatable every time at least on OpenBSD 5.9 and the latest snapshot
(July 17th), on amd64/bsd.mp using default installation.
