Hello there,

I am using VS 2008, SP1 in order to create applications for WM 5.0 +. The
applications are written in C++, no MFC is used.
I have a function in a dll that throws an exception of type class CEx. It
catches a reference to this exception, does some cleanup work and then
rethrows the exception. When calling this function from a different dll or
the main executable the application will crash, saying that the exception is
unhandled although the function call is properly enclosed in a try/catch
block.
Some additional points:
* If the called function does not catch and rethrow, the behaviour is as
expected (i.e. the application remains stable)
* If the thrown exception has a simple type like int, the behaviour is as
excpected
* If I move the called function into the calling dll or exe, the behaviour
is as expected
* If new is used to allocate the exception object and pointers to the
exception are caught, the application crashes as well
* If I explicitly rethrow the reference to the exception in the throwing
function then it works well, however a second call and throw makes the
application 'hang' and the debugger says that it cannot stop the debugging
session in the emulator

Steps to reproduce (platform: WM 5.0 or 6.0):
1) Create a WIN32 smart device console application
2) Create a WIN32 smart device dll, checking 'export symbols'. This will
create an exported class and an exported function in the dll
3) Add the member int  m_nCode to the created class and change the
constructor so that the code can be passed and set on construction
4) Throw an object of the class from the exported function, enclosing the
throw in a try/catch block. catch a reference to the exception (but without a
variable name) and do a rethrow
5) include the dll's header file into the application file
6) from _tmain call the exported function, enclosed in a try/catch block
7) make the application dependent on the dll
8) build and run in the emulator
9) the application crashes

Can anybody confirm this? What could be the reason?
The test solution can be supplied if necessary.
Many thanks
