Corrupt stack?

[Leon Pollak]

Hello, all.

I always receive the message "Previous frame inner to this frame (corrupt 
stack?)" from the kdevelop interface, when I break into the running program 
with Ctrl-C.
Running the same case in plane gdb (including "info frame" command) does not 
produce any error messages.

Where is the problem?

Below is the debugger printout:
