nikomatsakis (Jul 25 2019 at 13:36, on Zulip):

Hello, I'll run the meeting today. I'm starting pre-triage a bit late -- whoops!

nikomatsakis (Jul 25 2019 at 13:36, on Zulip):

We've got seven open P-high issues

nikomatsakis (Jul 25 2019 at 13:37, on Zulip):

None of which appear to be assigned

nikomatsakis (Jul 25 2019 at 13:38, on Zulip):

ICE: Generic type alias to invalid type crashes during type check on latest stable #62742

nikomatsakis (Jul 25 2019 at 13:38, on Zulip):

Stable-to-stable regression

nikomatsakis (Jul 25 2019 at 13:38, on Zulip):

Seems to have been caused by #48995

nikomatsakis (Jul 25 2019 at 13:39, on Zulip):

Probably something I should investigate, though that will be hard for me to do until August

nikomatsakis (Jul 25 2019 at 13:39, on Zulip):

Going to leave as is for now

nikomatsakis (Jul 25 2019 at 13:39, on Zulip):

Forgone caching in cycles caused much overflow in trait solving #61960

similar

nikomatsakis (Jul 25 2019 at 13:39, on Zulip):

ICE when running kcov with proptest as dev-dependency #60372

nikomatsakis (Jul 25 2019 at 13:40, on Zulip):

Probably a duplicate of "Encountered error Unimplemented selecting <...> during codegen #58375", which has been assigned to me for .. way too long

nikomatsakis (Jul 25 2019 at 13:41, on Zulip):

Skipping ahead to look for newer, burning problems

nikomatsakis (Jul 25 2019 at 13:41, on Zulip):

Stable rustc always panics on arm/musl #60297

nikomatsakis (Jul 25 2019 at 13:41, on Zulip):

Also quite old by now

nikomatsakis (Jul 25 2019 at 13:42, on Zulip):

looks like the action item is to find someone with access to arm/musl

nikomatsakis (Jul 25 2019 at 13:45, on Zulip):

Examining nominated issues

nikomatsakis (Jul 25 2019 at 13:46, on Zulip):

libcore fails to compile for thumbv6m-none-eabi #62932

nikomatsakis (Jul 25 2019 at 13:46, on Zulip):

stable to nightly regression

nikomatsakis (Jul 25 2019 at 13:47, on Zulip):

some comments, but generally failed to reproduce

nikomatsakis (Jul 25 2019 at 13:48, on Zulip):

Marking as P-high and request bisection

nikomatsakis (Jul 25 2019 at 13:48, on Zulip):

Segfault compiling libc on nightly-armv7-unknown-linux-gnueabihf #62896

nikomatsakis (Jul 25 2019 at 13:51, on Zulip):

marking as P-high, requesting bisection

nikomatsakis (Jul 25 2019 at 13:51, on Zulip):

ICE on "index out of bounds: the len is 3 but the index is 4" #62895

nikomatsakis (Jul 25 2019 at 13:51, on Zulip):

marking as P-high, has PR, assigned to @Esteban K├╝ber :tada:

nikomatsakis (Jul 25 2019 at 13:51, on Zulip):

ARMv6 architecture support broken in nightly-2019-07-18 #62841

nikomatsakis (Jul 25 2019 at 13:51, on Zulip):

@Nikita Popov thinks may be related to LLVM upgrade

nikomatsakis (Jul 25 2019 at 13:52, on Zulip):

looks like they also have a pending PR https://github.com/rust-lang/rust/pull/62904

nikomatsakis (Jul 25 2019 at 13:52, on Zulip):

great!

nikomatsakis (Jul 25 2019 at 13:52, on Zulip):

ICE on recursive struct #62838

nikomatsakis (Jul 25 2019 at 13:54, on Zulip):

looks like there is an attempt to minimize but no progress yet

nikomatsakis (Jul 25 2019 at 13:56, on Zulip):

marking as P-medium, maybe doesn't reproduce, not a regression

nikomatsakis (Jul 25 2019 at 13:56, on Zulip):

rls no longer builds after rust-lang/rust#62679 #62803

nikomatsakis (Jul 25 2019 at 13:56, on Zulip):

marking as P-high but @Igor Matuszewski is on it :tada:

nikomatsakis (Jul 25 2019 at 13:56, on Zulip):

Recent nightly versions break thumb* targets #62781

nikomatsakis (Jul 25 2019 at 13:56, on Zulip):

hmm another embedded issue

nikomatsakis (Jul 25 2019 at 13:58, on Zulip):

looks like it may be expected behavior

nikomatsakis (Jul 25 2019 at 13:59, on Zulip):

marking as p-high for now but requesting that @Nikita Popov and @James Munns close the issue if that is correct

nikomatsakis (Jul 25 2019 at 13:59, on Zulip):

ICE when use-ing enum variant after glob-importing same-named enum #62767

nikomatsakis (Jul 25 2019 at 13:59, on Zulip):

not cited as a regression, @Vadim Petrochenkov self-assigned, going to mark as p-medium for now

nikomatsakis (Jul 25 2019 at 14:01, on Zulip):

ICE using associated constant in generic type #62708

nikomatsakis (Jul 25 2019 at 14:02, on Zulip):

hmm fairly basic bug in associated constants

nikomatsakis (Jul 25 2019 at 14:02, on Zulip):

not sure how to classify this sort of thing

nikomatsakis (Jul 25 2019 at 14:03, on Zulip):

internal compiler error: src/librustc/dep_graph/graph.rs:688: DepNode Hir(...) should have been pre-allocated but wasn't. #62649

nikomatsakis (Jul 25 2019 at 14:03, on Zulip):

regression, stable-to-stable, something in the incremental system

nikomatsakis (Jul 25 2019 at 14:04, on Zulip):

@eddyb was investigating

nikomatsakis (Jul 25 2019 at 14:04, on Zulip):

I think I'll classic as P-medium but... not sure

nikomatsakis (Jul 25 2019 at 14:05, on Zulip):

well, it is a regr, i'll mark p-high

nikomatsakis (Jul 25 2019 at 14:05, on Zulip):

@eddyb how do you feel about being assigned?

eddyb (Jul 25 2019 at 14:57, on Zulip):

@nikomatsakis not that happy, I have no idea why that would ICE, I feel like I just exposed a pre-existing edge case
