Struggling with debugging a recursive function? You've set a breakpoint that should only break on a certain recursion-depth? This command is meant to rescue. Set it as action to a breakpoint with the depth you want the breakpoint to stop as argument, like continue_when_recursion_depth_not_equal_to 2 to stop on a recursion-depth of 2.
