Also may depend on the debug backend. Using FpDebug, you need to adjust the setting. In the Tools option > Debug backend => in the property grid: "HandleDebugBreakInstruction": disable the setting "dboIgnoreAll" On Windows you also have on OS function for that. But then you do stop in that function, instead of the caller.
