Summary0032157: Draw Harness - Use XSDRAWSTLVRML_DataSource cause a crash
DescriptionWhen I use XSDRAWSTLVRML_DataSource,it cause a crash.
The code like below:
Handle(XSDRAWSTLVRML_DataSource) aDs = new XSDRAWSTLVRML_DataSource(astl_mesh);


It runs okay,but when I close my application,it crashed in the file Draw_Interpretor.cxx.

Draw_Interpretor::~Draw_Interpretor()
{
  SetDoLog (Standard_False);
  if (myFDLog >=0)
  {
    close (myFDLog);
    myFDLog = 0;
  }

  // MKV 01.02.05
#if ((TCL_MAJOR_VERSION > 8) || ((TCL_MAJOR_VERSION == 8) && (TCL_MINOR_VERSION >= 4)))
  try {
    OCC_CATCH_SIGNALS
    Tcl_Exit(0);//crash
  }
  catch (Standard_Failure const&) {
#ifdef OCCT_DEBUG
    std::cout <<"Tcl_Exit have an exeption" << std::endl;
#endif
  }
#else
#ifdef _WIN32
  Tcl_Exit(0);
#endif  
#endif
}


My version of tcl is 8.6,the code check it and crash;

What happens?How can I do to solve it?

 I suppose this is irrelevant to XSDRAWSTLVRML_DataSource, and happens in Tcl itself. So the bug should be debugged there.

As for XSDRAWSTLVRML_DataSource in application code - it is better avoiding links to Draw Harness libraries as long as Tcl interpretor in not used in your application (cannot say if it does from bug description).
