Sorry, but there's nowhere near enough information for me to do anything with it.

• Can you explain how it "crashes"? Is the pointer null? Or does it crash when you call it?
• If the pointer is null, did you correctly initialize Magnum's context before?
• Does GL::DebugOutput::setCallback(Callback, const void*) work?
• Does the device support ES 3.2?
• If it doesn't, is KHR_debug supported? Is glDebugMessageCallbackKHR non-null?

I think I had a similar issue. For me it was trying to use the function before creating the context with tryCreate().

* Does the device support ES 3.2?

* If it doesn't, is `KHR_debug` supported? Is `glDebugMessageCallbackKHR` non-null?

it seg faults

ill try GL::DebugOutput::setCallback(Callback, const void*)
