The application failed to initialize properly ( 0xc0000005). Click on OK to terminate

[Terabyte]

Hi,
I'm using moc to manually compile a set of classes with slots containing Q_OBJECT macro,
I have added the resulting cpp files to my project, and compiled the project, it has solved a bunch of vtable errors i had before but now when i run the program I get The application failed to initialize properly (0xc0000005). Click on OK to terminate the application.

Anybody know why this is?

here is my code
abstract class called resourcebox

though there is only the connect function here and commenting it out doesnt fix it.

I am totally stuck on this one, dont know where to begin, thanks for any help

Please provide more information.
Which OS / compiler / additional DLLs?

I experienced this, when I used Qwt debug DLL with a release executable, e.g.

XP
Cygwin (G++)
Eclipse latest
No 'additional' dll's just the qt ones as added to the path variable

If you haven't already done that:
When you enter
"The application failed to initialize properly (0xc0000005)" cygwin qt
in google, you find some issues related to cygwin and qt and this error

I had a same problem ("The application failed to initialize properly (0xc0000005)") but with mingw.
Was my fault - forgetting to initialize the pointer with new before using it !

Hi, thanks for the reply, and yes I have checked that with no luck, or at least one of those results is mine on another forum, and hasn't received a response.
The other one that seems close is
http://lists.trolltech.com/qt-intere...ad00315-0.html
The original post is compiling qt on cygwin, and just - as most conversations about cygwin - resulted in some prat asking 'why would you want to do that' rather than knuckling down and answering the question.

Just for more information, If I remark out Q_OBJECT everything compiles and runs but I get the error along the lines of "something regarding slots/signals does not exist" which is fair, since it doesn't because the Q_OBJECT macro has been omitted. So pretty the error I get happens if I don't comment out Q_OBJECT.
