Hi again,

I was able to reduce the source to just 19 loc and two headers,
<sstream> and <boost/asio.hpp> (from libboost-all-dev 1.67.0.2).

Note that the reduced source does not compile and it didn't compile
when I first got the crash, but I guess that clang-tidy shouldn't
crash in either case.

Attached is source file and compile command database (need to adjust
paths). It crashes with default checks, e.g. just `clang-tidy a.cc`.
