I try virtual whit strut.
Interface Im,\ R, P, Stop Virtual at eax Som Im End virtual
Call [Som. Stop]
In Ida Pro I get call large dword 08h
But not call [eax+8]

interface don`t structurize data!!!
so, Som declared as object by single dword(or qword) in eax, and assumed that is pointed to interface structure.
But interface self is only abstraction - it is ALWAYS zero based structure.
Som = eax
Som.R = ptrsize*0
Som.P = ptrsize*1
Som.Stop = ptrsize*2
use "call[Som+Im.Stop]" instead.
[edited]I a bit hurried: even that is incorrect.
in eax+ptrsize located another variable.
so we for start should dereference ptr: mov eax,[Som]
and only after that call [eax+Som.Stop] ; Som.Stop equal to Im.Stop
