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

             Summary: Segmentation Fault with tproxy, tr-pass and garbage.
                 Key: TS-4754
                 URL: https://issues.apache.org/jira/browse/TS-4754
             Project: Traffic Server
          Issue Type: Bug
            Reporter: Tommy Lee


We have been suffering with a big problem here.

When client generates garbage and TR-PASS flag is set.

Trafficserver version is: 6.1.1 with these compile options: --prefix=/usr/local/cache-6.0 --disable-luajit --enable-tproxy --enable-hwloc --enable-debug --enable-static-libts

If it's necessary I can share my config files.


We get this segmentation fault:

traffic_server: Segmentation fault (Address not mapped to object [0x229])
