How to debug a windows app

[Gerhard W. Gruber]

I noticed that Agent crashes frequently when sending email. It shows an
exception which I never saw on Winodws because Agent is rather stable. Now I
want to take a look at it, but I need to know how I can debug a windows app
running under wine.

I think the best way is with logfiles created with the
--debugmsg argument to wine.
You can invoke the program under the wine debugger
by starting it with winedbg instead of wine,
but I have not yet gotten much use out of that;
log files are the way to go initially unless you know
for sure the debugger is what you want.

I need the debugger for usre. The problem is that agent throws an exception,
but it does that internally so I have to see what's going on. I can try the
logs first, though, but I'm intersted on how to do this anyway and sooner or
later I will need this.

Hmm, I use Agent every day. It does not crash frequently here, maybe
once per month at the most. Neither can I remember it crashing when
sending a mail. 
First rule of running agent stable is to use only builtin dll's. If you
have any windows dll's then check this with --debugmsg +loaddll , no
libraries should be loaded native.

I would try to catch the crash in the debugger first. A backtrace (type
bt) can give the first insight where the program crashes. If you didn't
set up the debugger then check out
