Hi Peter
I can recreate the problem by moving the */ such the "Added" comment is uncommented and the compiler (or IDE) does not generate and error and it does hang. There probably is some other combination involved because if you take just the comments and make a new sketch and verify, then the uncommented line is identified. I'll play with it more and see if the behavior changes but for now my problem seems solved.Thanks
Again, just to very clear. This is not a compiler or gcc tool problem.
This is a problem with the Arduino IDE and it's goofy parsing of the sketch code.
The IDE parses (or at least tries to) the sketch code and modifies it before any of the gcc compiler tools are used.
The sketch parsing routines in the IDE have MANY issues and those issues show up from time to time
depending on the code.
In some cases perfectly valid code with no errors in it can crash the IDE.
