Code

An error occurs when we try to build our code base under version 1.90 onwards, up to 1.92. The problem only happens in the release mode: a simple cargo build succeeds.

To reproduce, you can checkout Pathway:

git clone https://github.com/pathwaycom/pathway/

And run cargo build --release in the root directory of the repository with the version 1.90.0 or newer.

    Bisects to nightly-2025-06-29, which includes #142625. Same as #146965?!

    Not an MCVE, but for what it's worth I was able to come up with a tiny patch that works around the issue and builds under release in 1.92 (available in my branch).

    The main change is that I made the trait bounds in the relevant implementation stricter, which seems to help the compiler avoid resolving associated type projections too late during MIR optimization / monomorphization.

    Concretely, I changed

    Child<'c, S, T>: MaybeTotalScope

    to

    Child<'c, S, T>: MaybeTotalScope<MaybeTotalTimestamp = T>

    This equality does not appear to be semantically required at the language level, but it avoids the ICE in optimized builds.

    Hope that helps.
