In other repos Clang 14 with libc++ reports an ASAN failure: > AddressSanitizer: alloc-dealloc-mismatch - `free` in std::range_error::~range_error() (/lib/x86_64-linux-gnu/libc++abi.so.1...) - Allocated by `new` in std::runtime_error::runtime_error(std::__1::basic_string<...> const&) (/lib/x86_64-linux-gnu/libc++.so.1...)
Fix the `AddressSanitizer: alloc-dealloc-mismatch (operator new vs free)` false positive reported by recent Clang with libc++ by reverting to Clang 13. Fixes boostorg#167
