Funny, I studied on exact the same bug quite a while this morning.

I had the following case:

definition:
SUBROUTINE     SUB     0

and the call was in an if

IF x THEN SUBROUTINE

I discover this compiled to a conditional jmp instruction, resulting in a runtime error - retp without call or something like that (because the stack was empty).

I also found that changing this in

IF X THEN
    SUBROUTINE
ENDIF

compiled ok (resulting in a call instead of a jump)

Maybe this helps a bit..
