ICE: IndexSet: index out of bounds', /rustc/8460ca823e8367a30dda430efda790588b8c84d3/compiler/rustc_span/src/span_encoding.rs

[deepink-mas]

Put the following code in a new crate's src/main.rs and call 'cargo init'. Then 'cargo c' will ICE. I've tried to reduce further but it seems like if I remove any random line (even if it is a comment) the ICE goes away.

[deepink-mas]

I noticed there is an older bug that is probably the same: #100715.

[deepink-mas]

So like I said this ICE is extremely sensitive to the exact number of characters and lines. The contents of those lines seems to matter less; it is possible to replace most comment and identifier characters with another character (I tried 'x') as long as the total number of characters stays the same. Likewise, a tab can be replaced with a space.

The code that triggers is the last code line in this function (from https://github.com/rust-lang/rust/blob/1.68.1/compiler/rustc_span/src/span_encoding.rs):

    /// Internal function to translate between an encoded span and the expanded representation.
    /// This function must not be used outside the incremental engine.
    #[inline]
    pub fn data_untracked(self) -> SpanData {
        if self.len_or_tag != LEN_TAG {
            // Inline format.
            if self.len_or_tag & PARENT_MASK == 0 {
                debug_assert!(self.len_or_tag as u32 <= MAX_LEN);
                SpanData {
                    lo: BytePos(self.base_or_index),
                    hi: BytePos(self.base_or_index + self.len_or_tag as u32),
                    ctxt: SyntaxContext::from_u32(self.ctxt_or_tag as u32),
                    parent: None,
                }
            } else {
                let len = self.len_or_tag & !PARENT_MASK;
                debug_assert!(len as u32 <= MAX_LEN);
                let parent =
                    LocalDefId { local_def_index: DefIndex::from_u32(self.ctxt_or_tag as u32) };
                SpanData {
                    lo: BytePos(self.base_or_index),
                    hi: BytePos(self.base_or_index + len as u32),
                    ctxt: SyntaxContext::root(),
                    parent: Some(parent),
                }
            }
        } else {
            // Interned format.
            let index = self.base_or_index;
            with_span_interner(|interner| interner.spans[index as usize]) // *** THIS LINE ***
        }
    }

with_span_interner calls a function on the SpanInterner it gets from with_session_globals which gets it from thread-local-storage

// If an interner exists, return it. Otherwise, prepare a fresh one.
#[inline]
fn with_span_interner<T, F: FnOnce(&mut SpanInterner) -> T>(f: F) -> T {
    crate::with_session_globals(|session_globals| f(&mut session_globals.span_interner.lock()))
}

A SpanInterner wraps a FxIndexSet of SpanData:

#[derive(Default)]
pub struct SpanInterner {
    spans: FxIndexSet<SpanData>,
}

which is just an indexmap::IndexSet with the FxHasher (https://github.com/rust-lang/rust/blob/1.68.1/compiler/rustc_data_structures/src/fx.rs#L8)

pub type FxIndexSet<V> = indexmap::IndexSet<V, BuildHasherDefault<FxHasher>>;

The indexmap version is "1.9.2" (https://github.com/rust-lang/rust/blob/1.68.1/Cargo.lock#L2156)

[[package]]
name = "indexmap"
version = "1.9.2"
source = "registry+https://github.com/rust-lang/crates.io-index"
checksum = "1885e79c1fc4b10f0e172c475f458b7f7b93061064d98c3293e98c5ba0c8b399"
dependencies = [
 "autocfg",
 "hashbrown 0.12.3",
 "rustc-rayon",
 "serde",
]

The latest version is 1.9.3, but it does not seem to contain any relevant changes (indexmap-rs/indexmap@1.9.2...1.9.3).

indexmap uses hashbrown for its hashtable, which may mean that this bug ultimately comes from hashbrown.

[cjgillot]

A bug in hashbrown is very unlikely. Do you have a backtrace with symbol names?
This may also come from incorrect logic in Span::ctxt.

[deepink-mas]

@cjgillot Are you able to reproduce the issue given my test case? Can you explain what goes wrong?
