Hello, everybody,

there's a (probably copy-paste) mistake within the com64.inc. The macro comcall should not push an object handle onto the stack. Thus instead of
Code:
    macro call dummy
    \{ if handle eqtype rax | handle eqtype 0
      push handle
 local ..handle
      label ..handle at handle
    mov rax,[..handle]
       else
   mov rax,handle
      mov rax,[rax]
       end if
       call [rax+interface#.#proc] \}
    

there should be
Code:
    macro call dummy
    \{ if handle eqtype rax | handle eqtype 0
  local ..handle
      label ..handle at handle
    mov rax,[..handle]
       else
   mov rax,handle
      mov rax,[rax]
       end if
       call [rax+interface#.#proc] \}
    

This bug was discovered about a year ago by one of participants of another assembler related forum, but obviously was not reported here. I assume this little modification may be included into the next fasm release package.

Best regards
