The error I got with the latest version of rabbitmq-c was:

"A buffer overrun has occurred in z_rabbitmq_client_consumer.exe which
has corrupted the program's internal state. Press Break to debug the
program or Continue to terminate the program.
This is because you are trying to use a mingw build of librabbitmq from
Visual Studio. This doesn't work because VS and gcc disagree about x86
calling conventions. As a result, the program crashes is a way that VS
diagnoses as a buffer overrun.
I started VS 2010 debugging on a consumer project (c++) which uses the
rabbitmq-c c api.

I guess I finally found out at least the reason for my previous
error. I used a c++ wrapper (amqpcpp - modified) which calls
amqp_simple_rpc to implement the consumer, which then caused the error
(but runs correctly with DEBUG).

I modified the code to use amqp_basic_consume (following the
consumer.c), the c++ consumer application works now.

However, I still have the buffer overrun problem with the latest
version. I used MinGW to build the package. Do you whether there is a
guide/readme for cmake build?
There are some brief instructions in the rabbitmq-c README. In more

Install cmake (from <>). Then open up a command
prompt, create a build directory, and from there run cmake with the path
to the rabbitmq-c source directory:

Z:\>cd tmp

Z:\tmp>mkdir rabbitmq-c-build

Z:\tmp>cd rabbitmq-c-build

Z:\tmp\rabbitmq-c-build>cmake ..\rabbitmq-c

Then open up the rabbitmq-c.sln file in VS, and build.
