Encountered incremental compilation error with find_field(a5f984281f1e0bb0-ee8ea99685b18732)

[jflatow]

I cannot share the code, however since I was requested to file the unexpected panic in the compiler, I am attaching the stacktrace. This occurs when I change a bound from:
impl<G: H, T: N<G>> Trait<dyn N<G>> for T where T: 'static
to
impl<G: H, T: N<G> + 'static> Trait<dyn N<G>> for T

since you do have a reproducer, could you try it with RUSTFLAGS=-Zincremenral-verify-ich? that may pinpoint the bug

I've moved on in the project, so I can't run on exactly the same code, but I keep hitting roughly the same issue, here's another dump when I add that flag (seems not to change anything):

platform: aarch64-apple-darwin

Hitting these issues pretty constantly on this project, and actually, now seeing it happen that compilation is failing with some bogus error if I modify a macro, until I touch the test file which is using the macro, after which it compiles fine. Note the error in these cases is not a panic like above (which are still happening a lot), but a made-up complaint about the source code, which goes away after doing nothing but touching the test file. This makes me think it's possibly macros 2.0 related (which I am using)

[Noratrieb]

that sounds likely. I recommend you use normal macro rules instead and check whether that helps.

[jflatow]

I'll try converting when I have a chance, but assuming that is the case, linking to #39412 as it is still very buggy (happy to vet with this apparently devastating test case if/when it is believed to be more stable)
