It sounds like the ICE you had no longer occurs?  If so I'll close this bug,
feel free to reopen otherwise :)

You were right on both accounts, clearing the folder worked. The errors I'm
getting are real errors I believe, as copying more code from the vulkan
tutorial reduced the errors.
Now I just have to figure out how to get vulkan to work.

I can't reproduce the std.cc ICE. Sometimes such ICEs happen when there's stale
stuff in the ./gcm.cache/ folder. Can you remove this folder and see if the
std.cc ICE still happens?

For the vulkan_first_test.cpp errors, can you confirm that these errors aren't
present when using ordinary includes instead of modules? They seem like
legitimate errors instead of a compiler bug.

Here is the new output of putting the includes before the imports.
As you can see, the std module still has the ICE, but the main file does not,
instead, there are other errors.

i.e. place #includes first:

#define GLFW_INCLUDE_VULKAN
#include 
import std;
import vulkan_hpp;

Can you try swapping the order of #include and import in your
vulkan_first_test.cpp file? You may be running into PR99000.

Sorry for the late response. I could not preprocess the vulkan module interface
unit, so I uploaded it unpreprocessed.

Module interface unit

There is inconsistent macro definitions when I use -E to preprocess the file.

Can you provide the exact command lines in sequence to reproduce the failures?

Also provide the preprocessed source for the module vulkan_hpp ?
