Memory could not be read? (runtime) [solved]

[DrDonut]

Hi all,

So, I've just compiled a new version of a program that I've written earlier and that used to work just fine.

In this new version however, I've changed a lot of stuff.

It compiles just fine, the only warnings I get are "/* withing comment", so nothing critical.

When I try to run the program, I get the following error:
"The instruction at "0x6a340388" referenced memory at "0x00000001". The memory could not be "read". Click Ok to terminate the program, click cancel to debug the program."

Do you know what I did wrong?

The code is not too complex, it's just one window, no multiple threads, no file access whatsoever.

Here some info:
QT: 4.4.3
compiling: commandline
OS: Microsoft Windows XP Professional SP2

Thanks in advance
