Coredump from cargo with spirv_shader_passthrough feature

[tombh]

I'm trying out the new spirv_shader_passthrough feature and its giving me a coredump! Here's the last few lines of the logs:

I don't even know where to start with debugging this. There's no mention of anybody else ever having a "coredump" in the issues. If it's useful this is the diff of what I'm currently working on tombh/wrach@a19bcca

The only 2 things I can think of are; that spirv_shader_passthrough disallows WGSL, or that spirv_shader_passthrough uses too much memory. But I'm honestly lost here. Maybe I should try to reduce the size of the diff that causes the error.
