Next field not set to 0

I got the following warning from Vulkan:

ParameterValidation: vkCreateGraphicsPipelines: value of pCreateInfos[0].pStages[1].pNext must be NULL. This warning is based on the Valid Usage documentation for version 30 of the Vulkan header. It is possible that you are using a struct from a private extension or an extension that was added to a later version of the Vulkan header, in which case your use of pCreateInfos[0].pStages[1].pNext is perfectly valid but is not guaranteed to work correctly with validation enabled

Looking through your code, I saw that you did not explicitly set the Next field when you marshaled the structures. I fixed the warning by adding

    pointer->Next = null;

to PipelineShaderStageCreateInfo.MarshalTo to fix the issue I was having.

Looks like fall-out from the marshalling rework done for Linux/Xamarin - struct memory was originally zeroed when allocated, but that was swapped for explicitly initialising all fields. Guess I missed some! Will update the generator to fix.

Huh, actually subtler than that; memory zeroing still happens for individual struct allocates, but not for arrays. Either way, the fix is the same, let me know if that resolves your validate error.

That fixed it.
