I've had this happen to me as well (using other editors like Norton Editor).
I suspect that an errant character gets inserted (possibly due to EMI from
those arc welders next door) into the file. The editor won't display it, but
it gets compiled, causing problems.

Next time save a copy of the file, fix the problem, and then perform a
binary file comparison to see what the offending character is.
