Segmentation fault in QHash

Question

I got the following crash in QHash. I am unable to find any thing into. I am using Qtopia-Core-4.3.3 on Linux Machine.

The log is as follows:

ASSERT: "*node == e || (*node)->next" in file
/usr/local/Trolltech/QtopiaCore-4.3.3-400wrl/include/QtCore/qhash.h, line 824
Segmentation fault

Can anybody help me in this?

Actually,i do not know,from where this assert is being generated. It would be difficult to post the code,it is of 30,000 lines. — Ajay, Jun 19 '09 at 11:07
If you're using Windows and Visual Studio, run the application, break on assertion, then go to the last stack entry in you code. — Cătălin Pitiș, Jun 19 '09 at 11:13

Just a wild guess, but based on the fact that QHash is a container, and it is referring to "node", I think the given assertion is caused by the program expecting that the node is either the end node (e), or has a next node. So it appears something you are doing is messing up the entries in the hash.

To continue to speculate wildly, I have often seen some hard-to-diagnose errors when someone was iterating over a container, and sometimes removing things from the container while iterating. I don't know if QHash handles this nicely or not.
