Notably, the crash is while compiling a crate called cranelift-codegen, which suggests automatic code generation.

it’s funny you say this, because it’s a very reasonable assumption, but actually this is one of rustc’s codegen backends, as an alternative to llvm. the whole cranelift backend is actually optional, one easy hack would’ve been just to disable it in your config.toml

@jyn @rain cranelift-codegen and specifically the bits that seem like they were causing issues *are* code-generated code (they're part of isle, cranelift's instruction selection dsl). so cranelift-codegen does have parts that are code generated, even though "codegen" in the crate name refers to generating actual machine code

@iximeow @rain right, isle.rs is definitely autogenerated, that was a good catch by rain. but the rest of the crate isn’t, to my knowledge.
