[Qt-interest] line of code, where crush happens

[Sergey]

Hello,

I have QT program, built in VC2005

On my computer it is working well, but on client's it is crushing at 
unexpected moments of time.
Message is "An unhandled win32 exception occurred in Program.exe [4440]" 
and asks to select debugger.
What does number [4440] means?
I can not repeat it on my machine in the debugger.
How can i find out  line of code and call stack of error on client machine?
