Latest clang crashes building the MSSTL std module on Windows. git bisect shows the offending commit to be https://github.com/llvm/llvm-project/commit/cc5185bd146bed96d0d9e23263a56b6965d8572f. The crash appears to be a stack overflow, so the call stack isn't very helpful; all I can make of it is that it seems to be bouncing back and forth endlessly between `TraverseIfStmt` and `TraverseStmt`.
