The strace output suggests that the subshell is being killed by a SIGPWR
signal. I cannot tell why this signal is being sent to the subshell
though. Maybe the OS you are running on your embedded device is
sending this signal for some specific purpose and expects the application
to deal with it... In any case the fact that the subshell is not working
on your platform is not a bug in MC.
