-----------------------------------------
Another random thought: maybe something, somewhere needs to be made volatile.

> Key: AMQCPP-128
> URL: https://issues.apache.org/activemq/browse/AMQCPP-128
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Affects Versions: 2.1
> Reporter: Albert Strasheim
> Assignee: Timothy Bish
> Fix For: 2.1

> Attachments: main.cpp

> Attached is some code that does a few things with transacted sessions, in a
> loop. This sometimes reproduces the crash I mentioned in one of my latest
> comments in AMQCPP-122.
> I'm testing on Windows XP SP2 with Visual Studio 8 on Core 2 Duo machine.
> I've also seen all of the following happen in subsequent runs of the code:
> - Where I expect to receive a message, nothing turns up (even with a long
> timeout period). Cleanup goes fine.
> - Where I expect to receive a message, nothing turns up. Cleanup hangs.
> - Sometimes it prints:
> Mutex::unlock - Failed, not Lock Owner!
> FILE: ..\src\main\activemq\concurrent\Mutex.cpp, LINE: 83
> FILE: activemq-cpp\src\main\activemq/concurrent/Lock.h, LINE: 110
> FILE: ..\src\main\activemq\core\ActiveMQConsumer.cpp, LINE: 443
> FILE: ..\src\main\activemq\core\ActiveMQSessionExecutor.cpp, LINE: 192
> and keeps on going
> - Sometimes it crashes with the following when running a Debug build on
> Windows:
> ---------------------------
> Microsoft Visual C++ Debug Library
> ---------------------------
> Debug Assertion Failed!
> Program: ...
> File: C:\Program Files\Microsoft Visual Studio 8\VC\include\list
> Line: 776
> Expression: list erase iterator outside range
> For information on how your program can cause an assertion
> failure, see the Visual C++ documentation on asserts.

> Abort Retry Ignore

> - Sometimes it crashes with something along these lines:
> ---------------------------
> vs2005-activemq-example.exe - Application Error
> ---------------------------
> The instruction at "0x0053dd80" referenced memory at "0xdddddddd". The memory
> could not be "read".

> It crashes where it's doing resource->close() because resource points to
> garbage.
