----------------------------------------

             Summary: Segmentation fault in res_rtp_asterisk.so
                 Key: ASTERISK-20856
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-20856
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
            Reporter: Roberto Casas
            Severity: Critical
         Attachments: backtrace.txt

I have this bug in Asterisk 1.8.3.1 but I've inspected trunk version and the code is almost the same.

The bug is in the function:

ast_rtp_raw_write

When we have a remote_address, but frame->data.ptr should be 0 (because substracting hdrlen gives position 0xfffffffffffffff4 to the rtpheader variable)
