rust bootstrap ICE with debuginfo=2 #93866

Closed pnkfelix closed 3 months ago

pnkfelix commented 2 years ago

I tried a bootstrap with this config.toml, atop rust commit 502d6aa47b4118fea1e326529e71b25a99b0d6c5:

changelog-seen = 2
[rust]
optimize = true
debug = true

debuginfo-level = 2

then I ran this in a 

time x.py clean && time x.py build && time x.py test

I expected to see this happen: Successful bootstrap

Instead, this happened: ICE from compiler. (I think its the freshly built compiler, not the beta one.)

I'm wondering if this the same as https://github.com/rust-lang/rust/issues/93871 or if this is another cause.

pnkfelix commented 2 years ago

This bug appears like it was also injected by PR #93006, so that's a similarity with issue #93871.

However, I do not see the feature gate for unsized_tuple_coercion in the source code for libcore, so I am assuming that this represents a different bug injected by PR #93871.

I spoke to @michaelwoerister and I plan to revert PR #93871 based on these factors. It can reland after it has a successful bootstrap run with a config.toml of debuginfo-level=2.

michaelwoerister commented 2 years ago

Is this still relevant?

Triage: No one said "yes it is still relevant", so let's close a a obsolete.
