Disclaimer: I'm used to the kernel debugger, not EVC/PocketPC development,
so this may be way off base...
Put a simple printf() statement at the beginning of your app and load the
app up in the debugger, with a break point right before the printf. See if
you can step into the printf statement. This won't be all that helpful in
itself, but you should be able to put a break point on the printf function
implementation. When your app hits the offending rrintf statement for real,
hopefully it'll get hit in the debugger and you'll have a guilyt call stack.
On actual shipping devices that don't have a console, I don't think this is
a huge deal because the output will be redirected to the DEBUGOUT which most
of the time just is thrown into the bit bucket. However it would be cleaner
if you could remove any code that was doing printf()'s or at least get them
so the were in DEBUG code only. Also there's the danger you could disclose
some private information in these printf()'s that a bad guy could hook a
console/debugger into to retrieve.
