Re: [reSIProcate-users] Maybe a bug in DnsUtil

[Karlsson <boost.regex@xxxxxxxxx>]

It's iOS, here the error details in debugger:

Crashed: com.apple.main-thread
EXC_BAD_ACCESS KERN_INVALID_ADDRESS at 0x00000000

Thread : Crashed: com.apple.main-thread
0  libsystem_platform.dylib       0x322557b4 _platform_strchr + 12
1  Roamer                         0x0033978b resip::DnsUtil::getLocalHostName()
2  Roamer                         0x0033978b resip::DnsUtil::getLocalHostName()

So I guess may be the result is NULL cause app crash ?

In the DnsUtil.xx, below code:

      int res = getaddrinfo(buffer, 0, &hints, &result);

      if (!res) 

      {

         // !jf! this should really use the Data class 

         if (strchr(result->ai_canonname, '.') != 0) 

         {

            strncpy(buffer, result->ai_canonname, sizeof(buffer));

         }

      }

It's seems sometime the result is NULL will cause the app crashed.
