If you use the attached version with debug outputs (and enable the 24000 
debug area) you will see:

Quanta: numRows: 6
Quanta: Removing row: 5
Quanta: removeBreakpoint: remove row: 5
Quanta: Removing row: 4 <-- starting from here the breakpoints are not 
really removed!
Quanta: Removing row: 3
Quanta: Removing row: 2
Quanta: Removing row: 1
Quanta: Removing row: 0
Quanta: numRows: 5
Quanta: Removing row: 4
Quanta: removeBreakpoint: remove row: 4
Quanta: Removing row: 3
Quanta: removeBreakpoint: remove row: 3
Quanta: Removing row: 2
Quanta: removeBreakpoint: remove row: 2
Quanta: Removing row: 1
Quanta: removeBreakpoint: remove row: 1
Quanta: Removing row: 0
Quanta: removeBreakpoint: remove row: 0


I can reproduce this if I set/clear the breakpoints while the debugger 
is running. So actually, the problem might lie in the 
   if (bp->isPending() && !bp->isDbgProcessing())
check.

And might workaround seems to not work in every case. :-( Altough the 
above log suggest that all breakpoints were removing, in the GDB 
console I can verify that actually 3 are active. Maybe gdb must be 
stopped before removing the breakpoint? You know that code better, so 
hopefully you can find a real solution.
