There have been a few instances of the following error on i686-msvc on CI:

Assertion failed: !KeyInfoT::isEqual(Val, EmptyKey) && !KeyInfoT::isEqual(Val, TombstoneKey) && "Empty/Tombstone value shouldn't be inserted into map!", file C:\a\rust\rust\src\llvm-project\llvm\include\llvm/ADT/DenseMap.h, line 624
