context pointer always NULL for "c-tor" when created w/ Reflex::ClassBuilder::AddFunctionMember ?

hi there,

(still playing with Go)
I am seeing something rather strange:

say I have these structs:

/** edm **/
typedef struct {
  double E;
  double T;
} Det;

typedef struct {

  Det A;
  Det B;
} Event;

size_t g_sz_det = sizeof(Det);
size_t g_sz_evt = sizeof(Event);

and the corresponding c-tor stub functions: /* stub functions for Event */
void ctor_Event(void *retaddr, void *mem, void* args, void* ctx) {
  fprintf(stderr, "::ctor-fct[Event] [%p] [%p] [%p] [%p]\n", retaddr, mem, args, ctx);   void* dummy = 0;
  if (retaddr) *(void**)retaddr = (Event*)realloc(mem, sizeof(Event));   else dummy = (Event*)realloc(mem, sizeof(Event));   if (dummy) {}
}

/* etc... */

the ctor_Event stub function is attached to the Event Reflex::Type like so:
Reflex::ClassBuilder cb = ...;
Reflex::Type ty_ctor = Reflex::FunctionTypeBuilder(ty_void); void *ctx = &g_sz_evt;
cb.AddFunctionMember(ty_ctor, "Event", &ctor_Event, ctx, NULL,

                     Reflex::PUBLIC|Reflex::CONSTRUCTOR);

so far so good, and when iterating over the function members of the "Event" type I do see:
:: Evt-size: 32 32
:: Evt-mbrs: 2
:: Evt-type: 117
:: Evt-name: Event
:: Evt-id: 0x11c28d0
:: Evt-fct-mbrs: 3
:: fct-mbr[0][Event] - ctx [0x6033b8] stub-fct[0x401960]
:: fct-mbr[1][IsA] - ctx [0x11c3910] stub-fct[0x7f9892ed2290]
:: fct-mbr[2][ShowMembers] - ctx [0x11c3910] stub-fct[0x7f9892ed1d00]

ie: the correct address for both the context pointer and the stub function (calling resp. Member::Stubcontext() and Member::Stubfunction())

but when the ctor_Event function is invoked: ::ctor-fct[Event] [(nil)] [0x13b3500] [0x11c85d0] [(nil)]

the ctx pointer is always NULL, eventhough FunctionMember::Invoke does pass the fStubCtx to fStubFP:

   // parameters need more checking FIXME    fStubFP(retaddr, mem, paramList, fStubCtx);

(I'd like to use that context pointer to pass a few extra informations needed for the proper initialization of the Go runtime when instantiating the struct instance...)

am I doing something wrong ?
