Input related callbacks in GLFW cause an AccessViolationException

[vlOd2]

Summary

When setting any input related callbacks in GLFW, PollEvents causes an AccessViolationException

Steps to reproduce

• Platform: Desktop
• Framework Version: .NET 4.7.2
• API: OpenGL
• API Version: Legacy/OpenGL 1.1 (I mostly use Silk.NET to port legacy games)

1. Properly initialize a GLFW context and a window
2. Use either SetKeyCallback, SetMouseButtonCallback or SetCursorPosCallback (probably others too)
3. Call PollEvents

Comments

Oddly enough, SetWindowSizeCallback and other non-input related callbacks do not cause an access violation

// Leaving on this callback is fine
glfw.SetWindowSizeCallback(window, (WindowHandle* window, int width, int height) => 
{
	// Code is executed
	// ...
});
// But uncommenting this line, causes an AccessViolationException when polling the events
glfw.SetKeyCallback(window, (WindowHandle * window, Keys key, 
    int scanCode, InputAction action, KeyModifiers mods) =>
{
	// Code is not executed, game crashes
	// ...
});

Does the problem reproduce on .NET 6 or later?

This issue only happens on .NET Framework, not .NET 6+
