dlm and IDL_ExecuteStr

[Nando <f.iavarone(at)acsys.it>]

Hi all,
I was trying to use the IDL_ExecuteStr from a c module,
linked as a DLM.
The IDL_ExecuteStr seems to work,
but at the end of the execution the IDL interpreter out an error.

The function is:

static void testpro(int argc, IDL_VPTR *argv)
{
     IDL_ExecuteStr("a= 100");
     IDL_ExecuteStr("print,a");
 }

>From IDL:
ENVI> testpro
% Loaded DLM: TESTMODULE.
% TESTPRO: This is from a loadable module procedure.
     100
% Stopped on unknown instruction(96) at 1347620916.
% Execution halted at:  $MAIN$
ENVI>

If I call the xloadct all is OK:
static void testpro(int argc, IDL_VPTR *argv)
{
     IDL_ExecuteStr("a= 100");
     IDL_ExecuteStr("print,a");
 }

>From IDL:
ENVI> testpro
% Loaded DLM: TESTMODULE.
% TESTPRO: This is from a loadable module procedure.
% Compiled module: XLOADCT.
% Compiled module: CW_BGROUP.
ENVI>

Anyone have idea of what's happening?
Is it possible to use the IDL_ExecuteStr in a dlm technique?

Cheers,
