Setting break or trace statements causing Arduino to reset (Read 3987 times)

	Using 1605.28 plugin in VS2015 SP2 In one program I am getting a hang or auto reset when using VM debugging. I've tried everything to get it to work. To be clear, debugging works in my other programs using same board (Nano 328) and environment. On one point in time the program was overriding "OnSerialEvent" but no longer. Some ideas would be appreciated as I need debugging! Problem program attached.

	I #ifdef out a a lot of code and now on compile I get the following error after simply adding a breakpoint: Code (C++) DewMeNot.ino:In function 'void loop() controller_v312_HTU21D_BT.ino:2328:63: error: 'MicroDebug' was not declared in this scope :if ((tempcurrentMillis - _probe_prevMillis) > tempwaitdelay) { debugger: The error shown above might be caused by invalid breakpoint syntax or the board is not yet supported for debugging (pls let us know!) Error compiling project sources

	Ok came across a post about that compile error and re-organizing my header and defines fixed that issue. So now it seems that simple breakpoints do not break (at least no reset). But trace statements do cause the Nano to reset when hit. My trace statement is: Hello World

	Ok, got further. My project file named the same as my project was empty - my code was in another project file. Moved that code over to the main project file. I got basic trace to work (just some text), but trace with variable capture will reset the Nano. Breakpoint will not break. Disabled "Trace only..." debug setting had no affect.

	Holy crap, I think I figured it all out. Pre-processor defines are messing with things. 1) Even if something is #ifdef out, it would seem the compiler sill parses it somewhat. I had some code using a type that was #ifdef out and although that code was also defined out, I was getting compiler errors until I commented the code out as well. 2) Setting breakpoints or traces inside of a defined (i.e. compiled code) #ifdef block are ignored.

	Thanks for the update. I am sure others will find it very useful
