The set_data program limits the location and mapset to 25 characters
each (not including the terminating NUL). I suggest 256 for NAME_MAX
(most filesystems impose a limit of 255 bytes or less for filenames).

I can't think of a reliable way of locating undersized buffers other
than waiting for bug reports.
