Infinite loop when compiling http4s with -Ysafe-init-global flag

[q-ata]

Compiler version

Scala compiler version 3.4.0-RC1-bin-SNAPSHOT-git-55c2002 (commit 55c2002)

Issue

When trying to compile the http4s community project with the -Ysafe-init-global flag, the compilation hangs and appears to encounter an infinite loop.

The issue appears to stem from the cats project, which is a dependency and occurs when the checker tries to analyze the Eval object in Eval.scala.

I tried changing the definition of flatMap in Eval.scala:92 to some dummy value as follows:

def flatMap[B](f: A => Eval[B]): Eval[B] = f(value)

Doing so and recompiling http4s produces a stack overflow error instead of an infinite loop with the following stack trace:

... truncated due to length limit

A WIP repro: scala-cli test.scala

//> using scala 3.nightly
//> using option -Ysafe-init-global
//> using dep "org.typelevel::cats-parse:1.0.0"

import cats.parse.Parser

object Test:
  val alpha: Parser[Char] =
    Parser.charIn('A' to 'Z') | Parser.charIn('a' to 'z')

@main def run = println("hello")

Need to do further minimization.

[q-ata]

The specific code inside cats-parse that causes the issue is the function Parser::Impl::oneOfInternal in Parser.scala. This function in turn calls the List::traverse function from cats-core which causes the loop.

//> using scala 3.6.1
//> using option -Ysafe-init-global
//> using dep "org.typelevel::cats-core::2.10.0"

import cats.implicits._

object Test:
  val alpha: Int =
    List(1, 2, 3).traverse[Option, Int] {
      case _ => None
    } match {
      case _ =>
        5
    }

Need to investigate cats-core for a zero dependency test case.
