Consistent compiler crash, assertion failed while typechecking #19317

Open jgogstad opened 8 months ago

jgogstad commented 8 months ago

Compiler version

3.3.1

Minimized code

Small project for reproducing: https://github.com/jgogstad/spire-scalac-crash,

There is a chance that Spire is a culprit here, however, there are no traces of Spire in the compiler stacktraces, hence filing the issue here. See repo linked above for contained test case.

import spire.math.{Bounded, IntegralOps}
import spire.implicits.*

extension [A: spire.math.Integral] (a: A) {
  def coerce: Long = implicitly[IntegralOps[A]].coerce(a)
}

// this code isn't actually correct as far as calculating sizes goes as it doesn't account for closed and open bounds
extension [A: spire.math.Integral] (n: Bounded[A]) {
  def size: Long = spire.math.Integral[A].minus(n.upperBound.a, n.lowerBound.a).coerce
}

We should try to define the spire implicits and types in the example file to avoid the dependency.

nicolasstucki commented 8 months ago

@jgogstad could you compile it with the latest nightly build? That version should show more information on the assertion failure.

At least the crash is fixed. It is hard to know if this is an expected error from this snipped of code alone. We will need a minimization.

We should also check if the crash fix will be in 3.3.2. If not, we should backport it.

MateuszKubuszok commented 8 months ago

Similar issue got reported in Chimney, but without a working reproduction. I also assumed it is a compiler bug, since I feel it's unlikely that 2 libraries have the same bug at the same time.

ldeluigi commented 7 months ago

I'm experiencing the same issue

cptwunderlich commented 6 months ago

I just got the same error in a project using FS2 and cats-effect.
