What does exit code 250477278 of a Delphi application mean?

Question

We have a customer who has a problem, that our Delphi application does not seem to start. But we cannot reproduce it here.

The program however is starting, but immediate

Answer 1

That decimal value is, in hex, 0EEDFADE. That is the SEH code for a native Delphi exception. So, it would seem that your program is throwing a native Delphi exception that is not being handled. And it is doing so before the Delphi RTL exception handling mechanism is in place to deal with it.

It's impossible for us to say what in your code is causing this to happen, since we don't have the code. What you need to do is some debugging. You first of all need to identify the exception and work out where and why it is being raised. I would start by adding madExcept (or similar) to the project and collect some more information about this exception.
