FROM:	davis

BUG:	Apselect can sometimes fail with a segmentation violation if the
	input file has variable length records, (as can be the case for
	example if the user changes the number of apertures interactively,
	or if the user has defined polygons of various sizes)
	if the first record is not the longest record in the file,
	and if the size of the variable length record exceeds 20, the
	initial guess for buffer allocation.

STATUS:	The bug has been fixed in 2.10. There is no workaround except to
	ensure that the longest record comes first in the output file.
