Hi!

When building a .dll, the VC5.0 linker gives for each and every class of
my library a scaring warning:

Debug\mrt.def : warning LNK4102: export of deleting destructor "public:
virtual void * __thiscall t_VDRegularGridTravExact::`scalar deleting
destructor'(unsigned int)"; image may not run correctly

F1 tells me the following:

===========================================
Linker Tools Warning LNK4102

export of deleting destructor <symbol name>; image may not run correctly

The program has attempted to export a deleting destructor. The resulting
delete may occur across a DLL boundary such that a process can free
memory that it does not own. Make sure that the given symbol is not
listed in your .DEF file, and that the symbol is not listed as an
argument of the /IMPORT or /EXPORT option in the linker command line.
===========================================

Concerning this I have a few questions - because my image definitely
doesn't run correctly - :

1. What is the mangled name of a 'scalar deleting destructor', so that
   I can filter it out of my .def-File? I have tried a
      sed -e "/_Dt_/d" mrt.def > new_mrt.def
   but this didn't hit the right functions

2. How can a destructor delete anything in a DLL? Do DLLs have a heap
   of their own?

3. Is there maybe a cool linker option which filters all those awful
   destructors out, just giving me nice destructors which leave the
   free() call to the underlying c-kernel-lib as should be?

Any hints & pointers are welcome, Your's, Sven.

Try adding an operator new and operator delete to your exported class.
Hope this helps.
