DerelictGL3.reload(); crashes the application in release mode

[dkorpel]

When calling DerelictGL3.reload() after making a context for OpenGL, my application crashes when built in release mode. In debug mode it works just fine.

Example code: (glfw3.dll was taken from the 'lib-vc2015' folder and included in the same directory)

import derelict.glfw3.glfw3;
import derelict.opengl;

/+ 
dub.json:
{
	"name": "derelictGLissue",
	"dependencies": {
	"derelict-glfw3": "~>4.0.0-beta.1",
	"derelict-gl3": "~>2.0.0-beta.4",
	},
}
+/

int main() {

	DerelictGL3.load();
	DerelictGLFW3.load("glfw3.dll");

	if (!glfwInit())
	{
		glfwTerminate();
	}

	glfwWindowHint(GLFW_SAMPLES, 4);
	glfwWindowHint(GLFW_RESIZABLE, GL_TRUE);
	glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
	glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2);
	glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
	glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

	GLFWwindow* window = glfwCreateWindow(1280, 720, "Title", null, null);

	if (!window)
	{
		glfwTerminate();
		throw new Exception("Failed to create window");
	}
	glfwMakeContextCurrent(window);

	DerelictGL3.reload();

	while (!glfwWindowShouldClose(window))
	{
		glViewport(0, 0, 1280, 720);
		glClearColor(0.2f, 0.8f, 0.8f, 1.0f);
		glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

		glfwSwapBuffers(window);
		glfwPollEvents();
	}

	glfwDestroyWindow(window);
	glfwTerminate();
	return 0;
}

Running dub run succesfully shows a window, while running dub run --build=release results in an acces violation:

object.Error@(0): Access Violation
