I can't check $@ or override eval function to propagate die.
Why can't you check $@? This sounds like an artificial constraint. Why can't you simply branch and die if the eval fails, e.g. 
local $SIG{ALRM} = sub{die "Timeout hit\n"};
eval {
    eval {
        magick_die;
    };
    if ($@ and $@ eq "Timeout hit\n") {
        die $@;
    }
};

You could also fork and run the alarm in the parent thread. Then it really doesn't matter what the flow in the child is.
