I think here you should see, that the problem is somewhere between the
first and the
second strcpy. Probably you are doing some strange things which I cannot
see, because there are only some dots (and no code).

The best way to check out where the problem is, is to add the buffer
variable to the "Watchwindow" (in RHIDE Ctrl+F7) and after the first
strcpy
single step (F7 in RHIDE) through your code until you see any change at
the
variable, where it shouldn't.
