Maybe. It depends on how the application is built. If you use the VC++
"shared library" C++ runtime, then yes. If you statically link the C++
runtime, then no. The definitions of new and delete are defined in the
shared library.
Crossing EXE/DLL and even .lib boundaries with new/delete will _require_
the use of the shared library to link the application. One of the
indicators that this has occurred is the LNK2005 error message:
