[jira] [Created] (TS-735) Crash when searching on search.google.com
using ATS as forward proxy
Crash when searching on search.google.com using ATS as forward proxy
--------------------------------------------------------------------
Key: TS-735
URL: https://issues.apache.org/jira/browse/TS-735
Project: Traffic Server
Issue Type: Bug
Reporter: Leif Hedstrom
Priority: Critical
Fix For: 2.1.8
My setup is fairly simple, mostly standard configs, but setup as a forward proxy. When pointing my browser to use ATS as the proxy, and I go to search.google.com and start typing in the search box, we segfault.

[jira] [Updated] (TS-735) ccache can cause bad builds causing weird

Posted by "Leif Hedstrom (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-735?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Leif Hedstrom updated TS-735:
-----------------------------
Summary: ccache can cause bad builds causing weird segfaults (was: Crash when searching on search.google.com using ATS as forward proxy)
I'm changing the title of this crasher. After disabling ccache, and doing a completely fresh build, I'm not able to reproduce this problem. I'm going to make ccache optional from now on, developers can then opt in to use it to speedup frequent builds, but normal builds will not use ccache (for safety).
