> Segmentation fault possibly due leaks in atscppapi

> Key: TS-3821
> URL: https://issues.apache.org/jira/browse/TS-3821
> Project: Traffic Server
> Issue Type: Bug
> Components: CPP API
> Reporter: Jiri Podhorsky
> Assignee: Brian Geffon
> Fix For: 6.1.0
>
>
> Hello,
> I'm getting segmentation faults with ATS 5.3.1, possibly when I enabled
> plugins in atscppapi, in which are used other Plugins than GlobalPlugin
> (TransformationPlugin, InterceptionPlugin,...)
> i'm building traffic server only with parameters:
> ./configure --prefix=/install --exec-prefix=/exec --with-user=trafficserver
> --enable-cppapi
> I'm getting segfault:
> {noformat}
> traffic_server: Segmentation fault (Address not mapped to object [(nil)])
> traffic_server - STACK TRACE:
> /www/trafficserver/install/bin/traffic_server(_Z19crash_logger_invokeiP7siginfoPv+0x99)[0x4c64d9]
> /lib/x86_64-linux-gnu/libpthread.so.0(+0xf0a0)[0x2afbe25d90a0]
> {noformat}
> I tried to find an Issue and found possible leak in dectructor ~Transaction()
> of Transaction.cc file.
> The leak is, there is added plugin by addPlugin(TransactionPlugin *);
> and according to documentation
> [https://docs.trafficserver.apache.org/en/latest/api/classatscppapi_1_1Transaction.html#a9835e610553275d197cabfbd6d1cab7b],
> Transaction should be responsible for cleaning.
> But nothing removes items of list state_.plugins_, where should be pointers
> to memory allocated with new, which won't be deleted by delete state_;
> I tried to correct it with
> {noformat}
> for (TransactionPlugin* tmp : state_->plugins_) {
> delete tmp;
> }
> {noformat}
> But it didn't work. I'm getting similar segfault with another
> {noformat}
> traffic_server: Segmentation fault (Invalid permissions for mapped object
> [0x2b86141ea898])
> traffic_server - STACK TRACE:

> [0x2b86141ea898]
> {noformat}
> I tried to find more deep and find the plugins should be freed by delete in
> another class in file utils_internal.cc.
> But if this is true, I should see in debug mode message, which is printed
> before delete:
> {noformat}
> LOG_DEBUG("Locked Mutex...Deleting transaction plugin at %p", *iter);
> {noformat}
> But I don't see such messages in log.
> I can see in error.log lot of these messages. I'm getting them at least every
> second.
> {noformat}
> 20150805.16h37m04s [atscppapi] [Transaction.cc:343, operator()()] server
> request already initialized
> {noformat}
> Can you help me find the issue? Thanks for help in advance.
