	Hi everyone... I get a lot out of forums so I just wanted to contribute something I ran into and fixed. I suddenly got a compile error from Visual Studios 2017 when compiling a solution for a Teensy 3.6 with Visual Micro. It was complaining about a line of code in "mingw32.c". I assume that's one of the files I don't touch in the Program Files (x86) Arduino directory... Or somethings else... Definitely isn't something I had touched though. I went to the build menu and selected "clean solution" and the problem went away. In fact... that has fixed a few perplexing problems. Hope that helps at least one person!

	Thanks very much for the post! Out of interest, have you recently updated your teensy core?

	The day before I updated to Visual Studios 2017, then installed arduino 1.8.5, and reinstalled teensyduino. I had done several compiles after I completed all of those updates. The compile error seemed to come out of the blue... I went to lunch, came back, went to compile a few minor changes to my code, and I started getting: Quote: host-mingw32.c*:190: Attempt to access invalid address Cleaned the solution, and everything was fine.

	Maybe renaming or re-structuring your project could cause some confusion in the build folder but not heard of this before. Let's see if it happens again. Thanks

	Thank you TheStallionMang! I also encountered the same compile error and spent much time trying to figure which code change I did that caused the problem. Your solution fixed me right up! Thank you!

Thanks Here is a 'before fix' and 'after fix' verbose compile with build info. The 'fix' was to do a 'clean solution'.
