1084 Syntax error: expecting rightbrace before end of program.

Previous Animate Update introduced a few annoying glitches.  Recent update has corrected them, but now I am getting an error to an AS script file that previously ran (2 updates ago) without fail from another copied .fla. 

I am not going to insist that I dont actually have an syntax error, but I cannot find it, AND when killing the entire layer using /*, the debug posts the same errors.  (I didn't think it read/debug/compiled anyting after /*, ?)

Does anyone know of a something that could trigger the error, or is willing to look at the script and see if I have a legit sytax error needing a right brace - I may have been looking too long, and simply am not seeing it.  According to debug there are four(?), but it does not identify line or column:
