I am debugging c++ code from eclipse cdt helios version with gdb 7.1: The code IS actually executed correctly, but the line highlight behaves in the most schizophrenic way: instead of following the logic in my code, it jumps a few lines up and down or just skips them; it also delays updating variable values in the "Varibales" tab and printing my couts on eclipse's console.
It is really frustrating, especially since the "Varaiables" tab itself seems to be most uninformative: changes in most variables are updated straight away or their values read "<value optimized out>".
I installed support for printing STL containers (see http://sourceware.org/gdb/wiki/STLSupport). Could that be the cause of all this mess?

I am very puzzled.

??

Thank you,
Mattia

It sounds like you are debugging an optimized build of your code. Make
sure that you optimizations are turned off -O0 and see if you get the
same issue.
