Summary0013051: Using nonexistent objects in Standard_ForMapOfTypes class
DescriptionThere is a crash.
You can see two files in attachment:
 - import_prog.cpp - file for DLL library with import functionality;
 - main_prog.cpp - file for executable for testing functionality (dynamic
loading of previous DLL).

When You unload DLL before using BRepTools::Write (line 45 in main_prog.cpp)
it's generating crash in strcpm function caling from sorting of MapOfType.

When You unload DLL after using BRepTools::Write, all is OK.

Resume: When library is unloading, it needs for corresponding clearing of MapOfType.

Improvements:


Changes:
Static global map of types supported previously by Standard_Type class is
eliminated. In applications that load and unload some OCCT libraries
dynamically, this allows to prevent crashes caused by type objects created in
these libraries and remaining in the static map even after unloading of the
relevant library.

As a consequence of this change, static methods of that class providing access
to that map (Find(), Exists(), Add(), NumberOfKnownTypes(), GiveKnownTypeNumber
(), Display_Types()) are removed.

To allow checking type of object by its name rather than by Handle(Standard_
Type) object, the new methods are provided: Standard_Type::SubType() and
Standard_Transient::IsKind(). These methods replicate the same existing methods
accepting Handle(Standard_Type) but accept type name as Standard_CString.
