[jira] Commented: (AMQCPP-242) Segfault when destroying auto
pointer managed objects
[ https://issues.apache.org/activemq/browse/AMQCPP-242?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=51557#action_51557 ]
Martin Schlapfer commented on AMQCPP-242:
-----------------------------------------
Tim,
I was going to comment on AMQCPP-231, but saw this one open up, so I will comment here. I think the two are possibly related.
The AtomicRefCounter class release() method in Pointer.h is not thread safe the way it uses AtomicInteger::decrementAndGet(). The decrementAndGet() looks like:
apr_atomic_dec32( &this->value );
return this->value;
Between the two statements a context switch could occur. This could cause the value to be returned as zero in each thread to the caller. Thus, the AtomicRefCounter class release() method could try an delete an object twice.
Perhaps a fix is to introduce a new method that simply decrements and checks if the result is zero (using apt_atomic_dec32's return value).
Here is a sample program (below) to illustrate the problem (note on Windows I needed to put an apr_thread_yield() in between the two statements above to "force" a context swicth, but I suspect on RHEL you would not need to do that).
Cheers,
Martin.

> Key: AMQCPP-242
> URL: https://issues.apache.org/activemq/browse/AMQCPP-242
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: Integration Tests
> Affects Versions: 3.0
> Environment: CentOS 5.2, RHEL 5.2, apr-1.3.3, apr-util-1.3.4
> Reporter: Alexander Martens
> Assignee: Timothy Bish
>
> Looks like integration tests may cause occasionally segmentation faults (3 chances in 165 tries), specially when releasing aut_ptr managed objects. The following three gdb sessions show similar crashes.
> TestRegistry.cpp was modified to run only OpenwireSimpleTest by commenting all other tests out in order to narrow the problem.
> Hope this helps,
