How to Eliminate "warning: Unable to restore previously selected frame."

[babu198649]

Hi
i get warning message
warning: Unable to restore previously selected frame. when i debug the code in QtCreator ,What might be the cause of this? how to eliminate it.

[wysota]

Probably an incorrectly compiled application or debuging an application built in release mode.

Probably an incorrectly compiled application
Even after the application is rebuild i get the same error.

or debuging an application built in release mode.
The QtCreator executes the command
/usr/bin/make -f Makefile.Debug I can view the qt library files when i double click the stack trace produced by qtcreator ,but the libstdc++.so and libc.so are disabled in the stacktrace so does this mean that there is no libstd* debug libraries, which would have caused these warnings.

When exactly do you get those messages? And does it cause something to not work? It's just a warning, you know...

When exactly do you get those messages?
After the start of the program before anything is printed to console.The output looks like this.



warning: Unable to restore previously selected frame.

and more..(i have attached the almost(19.5 kb is the limit ) total output,)
no ..maybe.. because the program gets crashed even when build with release mode.
Can you guess what might be the error from the output of the error message of the program(The code is quite large ).

[wysota]

You get a segmentation fault. The backtrace looks fine, so you can probably ignore the warning and concentrate on fixing the error.
