digitalmars.D.learn - having troubles with D and Vulkan.

I am trying to run through the basic Vulkan triangle demo. I am getting stuck at
vkGetDeviceQueue which segfaults for me.
I have written the same tutorial to about the same point in C and I am
not getting the segfault.
I have enabled validation layers and they are not picking up anything.

Any suggestions?

I was able to get through the triangle demo a while back. I feel 
like it's more of a D question than a Vulkan library question. 
You'll have to post your code so people can tell what it is. Just 
a hunch, but it's probably something that the gc is collecting 
before it is used.

What's the best way to post code?

I am mostly not using the GC, using std.experimental.allocator
specifically mallocator to allocate other than using
std.exception.enforce.

What platform are you using, and how are you trying to build?

I can try to replicate on my end.

I am on Manjaro Linux with an AMD RX 6600 using the open source driver.
I am building with visual studio code and dub.
I get segfaults when building with dmd or ldc.

The following C code https://pastebin.com/2XJbjzMw
does not cause a segfault on the same system.

Other code you will need to build
https://pastebin.com/hx2GD1DL

Build settings (from dub.json)
{
"dependencies": {
"bindbc-opengl": "~>1.0",
"bindbc-sdl": "~>1.0",
"erupted": "~>2.1.98+v1.3.248"
},
"versions": [
"SDL_206",
"GL_32",
"validateVulkan"
],
"name": "subterrainian"
}

Redid the code as an almost exact translation of the C code.
should be easier to test and compare. Same issue is occurring.

ok found it, I am an idiot, (really not used to working with dynamic libraries).

erupted needs a call to load device level functions.

loadDeviceLevelFunctions(instance);

Same for me :) Great to see folks working in Vulkan with D.
