![]() ![]() I am testing LPM4.5, use C++, and use many assertions. Question: if I don't care to have an abort message, is overriding the definition of _abort_msg() the conventional way? And how would I then invoke the debugger?įor a production build, I substitute an implementation of assert() that typically does a software reset. Why is this different than a breakpoint and why would you use it Generally you. Which very slightly skews memory sizes and power use while using EnergyTrace. A direct call to a debug break can be used to stop the execution of a program. data segment which seem to get initialized at C startup. What I do care about is that these functions don't have any useful effect, but they seem to drag in a lot of code such as write() and _stream from the runtime library. I don't understand how that invokes the debugger, but I don't really care, as long as it breaks into the debugger as if BKPT was invoked. fputs(), _abort_msg(), assert()Īnd the program counter is at this line of _TI_writemsg():įor (i = 0 i < 8 i++) PACKCHAR(*parm++, p, i) When assert() is called and you ARE debugging (say a Launchpad, and using the debugger, even when no breakpoints set), I find that assert() ends up pausing the target, and shows a stack trace of: ![]() If you choose Retry in the message dialog box, CrtDbgReport returns 1 and CrtDbgBreak calls the debugger through DebugBreak. Some questions and comments related to the linked post. If the asserted expression evaluates to FALSE, CrtDbgReport is called to report the assertion failure (using a message dialog box by default).
