Hi,
=0A=
 
=0A=
we're facing strange problems with a = dll using axis-c (1.6b) on win32 machine.
=0A=
 
=0A=
1) We built a simple exe using the = Calculator client class which works well.
=0A=
2) We built a dll version with = __stdcall convention which causes problems.
=0A=
- We first built the dll without the = /MD compiler flag. It worked but with strange effects. (Memory was = overwritten during the instantiation of the Calculator = class.)
=0A=
- we than built the dll with /MD = flag which resulted in the following error:
=0A=
exception in calclib: DLOPEN FAILED in loading parser library = Failed to load parser within server = engine:
          &n= bsp;      Error Message=3D'Invalid access to = memory = location.
'          = ;      Error = Code=3D'998'
         &nb= sp;       Load lib error=3D''
=0A=
 
=0A=
The code of the dll is:
=0A=
 
=0A=
int __stdcall add(int pOne, int = pTwo) {
  char *tst =3D NULL;
  Calculator *calc =3D = NULL; // static memory overwrites the stack!!!
  int rc =3D = 0;

  try {
    calc =3D new = Calculator();
=0A=
    rc =3D = calc->add(pOne, pTtwo);
    delete = calc;    
    return rc;
  = } catch (exception &e) {
    printf("exception in = calclib: %s\n", e.what());
    return -1;
  = }
=0A=
}
=0A=
 
=0A=
Caller:
=0A=
 
=0A=
int main() {
  int rc = =3D 0;
  int one =3D 10;
  int two =3D 35;
  try = {
=0A=
    rc =3D = add(one, two);
  } catch (exception &e) = {
    printf("Exception in calc: %s\n", e.what()); =
    return -1;
  }  
  if = (rc > 0) { // it's just a simple test, so we're using = values > 0 only
    printf("Result: %d\n", = rc);
    return 0;
=0A=
  } else = {
    printf("Error: %d\n", rc);
    = return -1;
  }
}
=0A=
 
=0A=
The header for both:
=0A=
extern "C" int __stdcall = add(int, int);
=0A=
 
=0A=
From the makefile:
=0A=
calclib.obj: calclib.cpp = Calculator.hpp
 cl -c /MD /DWIN32 -GX = /Ic:\ts\axis\include calclib.cpp
=0A=
