QModelIndex destructor causes "user breakpoint"

[wysota]

Are you using an IDE to build your application? It looks more like you set a breakpoint somewhere in the IDE than a problem with the application code. Try using commandline tools to build and execute your application and see if the problem persists.

I use VC++ 2003, the problem was the fact that (for some reason) my runtime libraries were not set to multithreaded DLL.

I didn't set any breakpoints, this user breakpoint is caused by Qt runtime checks in the VC++ debugger (done on purpose when there are heap memory problems I guess).

Thanks anyway.
