Another update with F# 1.9.6.2 and mono 2.2:

> let rec map f l =
    match l with
    | [] -> []
    | h::t -> f h :: map f t;;

val map : ('a -> 'b) -> 'a list -> 'b list

* error while converting instructions to code for method: map


error FS0192: internal error: a tailcall must be followed by a return, instrs =
