When I have two breakpoints in the same file, say 1 and 2, and I delete 1, 
then delete 2. What happens is that first 1 is deleted, but when I delete 2, 
the first is restored back!
Below is the gdb "show all" printout:

The lines after "break-delete 4" appeared at the moment of the second BP 
deletion.
Deletion of breakpoints via the "bp tab" does not help - they are restored 
somehow and appear as a gray circles... And sometimes bp is set but not 
displayed...

I have this happenning many many times. i should say that correct behavior is 
much more seldom then incorrect.

For me works only in one file till now. I can not say what is special in this 
file against others.

What do you mean? You too have them all gray? Or vise verse?

Yes, I have 6.6. 
Below is the session printout. Hope it will help...
