Why does Debug Utils Extension requires swap chain device extension?

I want to use a new VK_EXT_debug_utils. I did it in a couple of projects already and it worked fine, but today I found that vkSetDebugUtilsObjectNameEXT throws a SIGSEGV. I spent a good amount of time trying to figure out what were differences between a new project and the old ones. With blind attempts, I figured out that in the new project I didn't specify VK_KHR_SWAPCHAIN_EXTENSION_NAME when created a device (because I don't need it) and that caused a crash somehow. I searched in a documentation but could not find any mention of this behavior. Did I miss something important?

Upd.: on Windows, the problem exists as well.

(Edited: Now fixed) I just saw this issue. I looked into it quickly by modifying one of Sascha Willems examples and I was able to reproduce this. It is a Vulkan loader bug, not a driver bug. I created a Vulkan loader bug here and resolved the issue.

If you build your own Vulkan loader, you can get a fix now. Otherwise, you'll have to wait for our next SDK release.

Sorry, but a huge thanks for catching this.
