Description
When compiling paritytech/parity-common workspace using cargo test --features std.
As far as the error shows it has something to do with the patricia_trie sub crate.
Compiler output:
error: internal compiler error: broken MIR in DefId(0/0:377 ~ patricia_trie[2708]::Trie[0]::is_empty[0]) (NoSolution): failed to normalize `<_ as hashdb::Hasher>::Out`
