You didn't say whether your API project is a DLL or static library. Same for
wxWidgets. But anyway you apparently have 4 projects, and you have to either
somehow make sure they all use the same memory heap, or if there is more
than one heap, you never allocate from one heap and free it to another. One
thing you can try is to trace into the new/delete calls and see if they do
end up calling the same memory allocation/deallocation routines (use
disassembly to check the function addresses).
And here is sample code for GetNewAndDeleteForCryptoPP, if you want to try
that.
extern "C" __declspec(dllexport) void __cdecl
GetNewAndDeleteForCryptoPP(PNew &pNew, PDelete &pDelete)
{
pNew = &operator new;
pDelete = &operator delete;
}
