Returning Strings from DLL Functions

Question

For some reason, returning a string from a DLL function crashes my program on runtime with the error Unhandled exception at 0x775dfbae in Cranberry Library Tester.exe:

Answer 1

This occurs because you're allocating memory in one DLL (using std::string's constructor), and freeing it in another DLL. You can't do that because each DLL typically sets up it's own heap.
