Message 1 in thread

Ok... I don't totally understand this error. My program loads a UI 
discription from a shared object (plugin), which is just a list of widgets to 
create with optional lables, optional default values, and an optional group, 
(widgets are limited to GroupBox, LineEdit, CheckBox, and SpinBox), they are 
all placed into a GridLayout which is where I think the problem stems from, 
because the trace back in gdb crashes while creating a GridLayout...

#17 0x40618af0 in qFatal () from /usr/lib/libqt.so.3
#18 0x40618bb6 in qt_check_pointer () from /usr/lib/libqt.so.3
#19 0x4061274d in QGArray::resize () from /usr/lib/libqt.so.3
#20 0x403bf04f in QGridLayoutData::setSize () from /usr/lib/libqt.so.3
#21 0x403be8c7 in QGridLayoutData::QGridLayoutData () from /usr/lib/libqt.so.3
#22 0x403c1ac9 in QGridLayout::init () from /usr/lib/libqt.so.3
#23 0x403c15af in QGridLayout::QGridLayout () from /usr/lib/libqt.so.3

The funny thing is it doesn't crash the first time I create a the Dialog but 
the second. I 'delete' or 'close' the Dialog, but it doesn't seem to kill any 
of the child widgets. especially the Layout.

thanks,

Has anyone seen that problem before? Is it my fault?
Do I need to post more information? Should I use all CAPS for my next 
subject? ;)

Looks like the compiler fucked up due to lack of memory.
Search the mailing list.
And seems to be your fault ;). Buy memory! (no, just kidding here).

Yepp!
1. Qt version
2. operation sytem + version (win/unix/linux???)
3. In this case: hardware, especially amount of memory installed
4. compiler + compiler version (gcc or what?)

Oh, please, do not.

I'm not quite sure if it is a similar problem: on win98/Me happens the 
following:
we are using screens with buttons inside, which have bitmaps. We are 
switching from one screen to another. We are using the bitmap-cache of qt.
Sometimes some bitmaps disappear, also icons of other applications are 
gone. When I press ALT-TAB to switch apps, even these icons are gone. 
Then I know I have to quit all apps, or I have to reboot soon.
Is this a feature of win98 or a problem in the memory functionality? I 
have really no idea.On other systems it works.

Thomas: you are sure that you always set the correct parent of your 
members? So that they are correctly deleted?
