Compilation ICE on nphysics crate #33096

trolleyman · 2016-04-19T16:52:27Z

When trying to compile nphysics on a nightly created on or after 2016-04-14, the compiler errors. Before this date it is fine.

Example code:

git clone https://github.com/sebcrozet/nphysics
rustup update nightly-2016-04-13 && rustup run nightly-2016-04-13 cargo build # Works fine
rustup update nightly-2016-04-14 && rustup run nightly-2016-04-13 cargo build # Errors

Presumably was this commit that broke things, as it's a commit on that day that touches trans.

On Windows 64 bit GNU this is the output:

   Compiling nphysics3d v0.2.2 (https://github.com/sebcrozet/nphysics.git#b379109f)

You sure it's that innocent commit and not, you know, my changes to debuginfo, for MIR?
Specifically, this normalization is gone, that could cause problems.

eddyb · 2016-04-19T18:59:17Z

@trolleyman I can't reproduce on master (just rebased one of my branches containing unrelated changes, so I had a compiler to check with).

EDIT: Still no reproduction, even after git checkout b379109f.

trolleyman · 2016-04-19T20:13:23Z

Ok so I was misinterpreting which crate was being compiled. nphysics compiles fine, but my crate, which uses nphysics, doesn't. I'm trying to narrow down the code now.

Here's some of the rust log that I got when compiling on debug builds:

eddyb · 2016-04-19T22:17:58Z

@trolleyman That's not really helpful, sadly, nightly doesn't use -C debug-assertions yet, so there's no debug! output.

eddyb · 2016-04-19T23:17:33Z

@trolleyman This bug is not in beta, correct?

trolleyman · 2016-04-20T00:17:49Z

@eddyb I'm afraid that I can't test that as I'm using #[feature]s.

eddyb · 2016-04-20T00:20:29Z

@trolleyman Can you check the test from #33099 instead? Particularly interested about the nightlies you had issues with.

trolleyman · 2016-04-20T00:26:38Z

@eddyb Sure, unfortunately that test case works fine for both pre and post-2016-04-14.

eddyb · 2016-04-20T00:28:39Z

@trolleyman Ah, beats me then.

trolleyman · 2016-04-20T00:29:52Z

@eddyb I'll try and find which part of my code hits the error.

trolleyman · 2016-04-20T12:14:42Z

@eddyb So I did some digging and I was wrong again, it turns out it is the nphysics crate. This is a minimal test case:

extern crate nphysics3d;

pub fn main() {
    nphysics3d::world::World::new().step(1.0);
}

eddyb · 2016-04-20T14:24:35Z

@trolleyman It depends on the nphysics3d crate, but it's not the crate itself, and that testcase is still large in terms of how much it needs to monomorphize.

trolleyman · 2016-04-20T23:51:10Z

@eddyb True, sorry but I am not knowledgeable at all in rustc or nphysics, so it's the best I can do :/

nikomatsakis · 2016-04-21T20:09:30Z

triage: P-high

Normalize types before using them in debuginfo. Small oversight, fixes #33096 - odd thing is that the old code doesn't look like it should've ever worked, although it wasn't using all of the type parameters, so maybe that's what changed.

eddyb · 2016-04-26T10:38:21Z

Still need a good regression test.

nikomatsakis · 2016-05-05T18:52:07Z

triage: P-low

Mark-Simulacrum · 2019-09-01T14:22:39Z

I'm going to go ahead and close this. It's somewhat unlikely we'll hit this again (at least, we haven't obviously done so in the past 3ish years), and coming up with a good test case when the current case is all of nphysics is likely to be quite hard.
