Hello Nicolas, hello Jerome, hello list :)

Even an early alpha version of the IDA Windows CE debugger proved
to be *very* useful and had some major advantages over the
Embedded MSVC debugger (single-stepping into subfunctions for instance).
I used IDA and the CE debugger in order to find and verify the
vulnerability mentioned above. Looking forward to 4.9 :-)

Cheers,
