A clear and concise description of what the bug is.

Cannot navigate into the source of dll built with Debug. Error produced.

To Reproduce
Please include a code sample and launch.json configuration.

Library

//// lib.h
#include <iostream>
class __declspec(dllexport) Test
{
	public:
	Test();
};

//// lib.cpp
#include "lib.h"

Test::Test()
{
	printf("Hello world");
}

Client App

//// src.cpp
#include "lib.h"

int main()
{
	Test *a = new Test();   // breakpoint set here; and then F11 is pressed
}

La issue non indica alcun file sorgente o test. Inizia riproducendo il progetto CMake fornito con il launch.json mostrato, quindi analizza la traccia del debugger intorno alla pressione di F11 da src.cpp verso test_lib.dll. Il lavoro è terminato quando la navigazione nel codice sorgente della DLL non causa più il crash del debugger.
