Timothy Bish commented on AMQCPP-128:
-------------------------------------
I spent some time looking at this again yesterday. Looks like there may be an
issue with the Windows code for the Mutex class, not sure what it is yet
though. This never happens on Nix systems. I'm trying to create a Mutex class
unit test to replicate this in hopes of making it a little easier to see what's
going on.

> 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

> 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.

> - 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".
