Qt Creator crashing at start the application debugging and dont generate crash report

[_dmp]

I use QtCreator at Qt5.2.0 installation.
When I start the application debugging, QtCreator is crashing with message:

@mycomp: /opt/Qt5.2.0/Tools/QtCreator/bin$ ./qtcreator
\Segmentation fault(dump was created)@

I dont see any crash report. Where I can find it?

I use Ubuntu 12.4

P.S. before run QtCreator I run
@ulimit -c unlimited@

please help

Hi, in similar cases I've tried to find the line where the crash happens through breakpoints in debugging and this always helped clearing the issue.

[_dmp]

But I cannot run my application with debugging )
When I run the debug my application Qt Creator crashes at this time

Does that mean it crashes even you set a breakpoint in one of the first lines? Is it a complex application with plugins?

[_dmp]

Yes! I have breakpoint in main.c in first line and QtCreator crashed.

[_dmp]

So how I can see crash report or memory dump?

[clochydd]

In ubuntu it should be located in the working directory, called core.
You may find some hints to possible alternatives "here: ":http://stackoverflow.com/questions/2065912/core-dumped-but-core-file-is-not-in-current-directory

on my system was GDB 7.1.
I update rigth now to 7.6 and now I can use breakpoints. Hura!
I get crash still at point QQuickView view;

@QQuickView view;
view.setResizeMode(QQuickView::SizeRootObjectToView);
QQmlContext *ctxt;
ctxt = view.rootContext();@

there are any considerations?

I can only suggest to search the debug information and generate a new thread in the Qt Quick forum with a hint to the function from the Threads View.
