Can't declare more than 7 QStrings ?!?!?!

Hi all!

I am struggling with a problem that I have never seen before. I need to declare 14 QStrings but I can only declare 7, because as soon as I declare 1 more my code crashes at the beginning.

This is how the header file looks like:

As you can see some of my QStrings are commented because I can't run the program if they aren't.

If it helps I am using Eclipse Helios with qt 4.5.0 on ubuntu 9.04 32 bits.

Thanks

look at your delimiters in your string list... you have some ";" instead of ","

if that was the problem the program would not even run.
I just have some with ; and other with , because that's where I stop to test

Why are you subclassing QThread? Inherit QObject instead and create a normal QThread object.

I got it woking but I still don't know why I got the errors. It works with the class inherited from the QThread

There is some memory corruption problem.
Check for instances where you are creating and deleting the objects of your class.

but now it works...I wish it didn't so I could see why. I have no idea why it works now

I also don't think it was a problem with a delete because I had none

You probably didn't recompile part of your project after adding strings and the size of your object changed enough to change relocation offsets of some method, hence the crash.

That seams possible to me
