Address Sanitizer exception on hello world example #539

Closed lookbusy1344 closed 1 year ago

lookbusy1344 commented 2 years ago

I was trying the hello world example with VS2022 and Address Sanitizer. When I request 127:0.0.1:18080 in Edge browser, I get an Asan error.

Its caused by the request for “/favicon.ico” which seems to sometimes have whitespace (\x10 or \x13) at the end. For some reason this causes qs_parse() in querystring.h to cause an asan error on the calls to strcspn(). I bodged a fix by stripping whitespace from the end of url in the query_string constructor. Is this just an artefact of Microsoft’s Asan implementation. Any thought?

Can you provide details? Which compiler and its version, the trace returned by ASAN showing line numbers, etc.?
