Coturn server crashes

[watanabejr]

I build source code coturn and libevent, then install them in CentOS 6.5. STUN and TRUN access seems to be working correct.
But, when I send http query request without "=" and value like http://<ip address>:<port>?key, coturn server crashes because of segmentation fault.
Coturn server does not crash when I send http query with ?key= or ?key=value.

Here is the syslog.

I want not to stop coturn when the server receives any query.
Is this a bug? Otherwise, could you please tell me how to avoid?

Thanks.

Thank you for the quick response.

I confirmed that coturn does not crash when I send query of this issue.
But, it seems any http response is not returned to my client. Is it a correct behavior?

[mom040267]

not "any", only badly formed HTTP requests.

I'll adjust it so an error will be returning.

Sorry for my poor English.

I confirmed that logon page is returned when I send bad format HTTP requests.

Thank you for your time.
