Thanks for the report.  Can you run the equivalent of strace to see what
is being attempted when exec'ing the child process?  Or maybe this is the
case of a spurious errno value being left over from some earlier syscall.

I'll try and get on a FreeBSD machine and see if I can reproduce this.
But my initial pre-release testing on BSD did not fail, so I will have to
figure out what is different between my environment and yours.
