Package: llvm-7 Version: 1:7.0.1~+rc2-1 Severity: grave I've just updated my Sid install and found that building Rust crates with Cargo now fails with a seg fault.
Initially I fired a bug report at cargo to kick things off, but I've now discovered that it relates to the llvm-7 update, as switching llvm7 packages back to testing versions fixes the problem.
