ICE: "assertion failed: *old == value" in optimized + incremental builds

[BobG1983]

Repro:

Rustc Version: rustc 1.81.0-nightly (59e2c01 2024-06-17)
Toolchain: nightly-x86_64-pc-windows-msvc

What I did:
Clone https://www.github.com/BobG1983/rantz_random.git
run cargo test
run cargo test again.

Issue:

The compiler panics with the following output:
