Process aborted. Segmentation fault

Hi all,
I am using Qt 4.2.1 on LINUX(SUSE 10.2). I am getting the segmentation fault runtime error when I open a MDI child window second time.
What could be the reason for segmentation fault error.
Thanks in advance.

Can you give some debug info or code?

I am having an MDI application, when first time I am opening the child window, its runnig fine but when I try the second time to open the child window then program crashes.
I am creating the child window using new operator.

I think you need to post some code.
Like the constructor and any initialization code you might have.

Regards
