See in particular https://github.com/cuddlefish-io/cuddlefish/blob/6214d031f1070af381a9cd65981e3555286e44f0/api/src/hasura.rs#L34.

[samuela]

For some more context, this GraphQL query is known to be good. After a little poking around this seems to be caused by the type of the argument.

[tesuji]

Can you check the code in nightly Rust?

[Julian-Wollersberger]

I could reproduce this in todays nightly, the nightly from 2020-07-26, stable 1.45.2 and a very old nightly from 2020-01-14.
This stack overflow seems to exist for a long time.

This looks like infinite recursion in the proc-macro graphql_client_codegen

[Julian-Wollersberger]

Yes, it's infinite recursion in a proc-macro.

Minimal reproducer

File stackoverflow_proc_macro/src/lib.rs:

extern crate proc_macro;

use proc_macro::TokenStream;
use std::str::FromStr;

#[proc_macro_derive(GraphQLQuery)]
pub fn hello_macro_derive(_input: TokenStream) -> TokenStream {
    TokenStream::from_str(&recursive_call(42).to_string()).unwrap()
}

fn recursive_call(n: i32) -> i32 {
    return recursive_call(n + 1);
}

File stackoverflow_proc_macro/Cargo.toml:

# [package] ...
[lib]
proc-macro = true

File api/src/main.rs:

use stackoverflow_proc_macro::*;

trait GraphQLQuery { }

#[derive(GraphQLQuery)]
struct InsertBlamelines;

pub fn main() {}

File api/Cargo.toml:

# [package] ...
[dependencies]
stackoverflow_proc_macro = { path = "../stackoverflow_proc_macro" }

This results in the same error message:

    Compiling stackoverflow_proc_macro v0.1.0 (/home/julian/Dokumente/Rust/ICEs/cuddlefish/stackoverflow_proc_macro)
    Checking api v0.0.0 (/home/julian/Dokumente/Rust/ICEs/cuddlefish/api)

thread 'rustc' has overflowed its stack
fatal runtime error: stack overflow
error: could not compile `api`.

Caused by:
  process didn't exit successfully: `rustc <very long command> ` (signal: 6, SIGABRT: process abort signal)

This is just a missleading error message: It doesn't happen in rustc directly.

[samuela]

So it seems like this is the kind of thing that should be reported as a proc-macro error then. The current error message is a bit misleading since this isn't directly rustc's fault.

[nagisa]

Yeah, I’m going to call this a

It has been a long-time desire/want to isolate proc-macros from the rest of rustc better, but its… not trivial.
