[DebianGIS-dev] Bug#542171: hdp dumpvd segfaults when the filename is too long

[Ivan Shmakov]

Package: hdf4-tools
Version: 4.1r4-22

	hdp(1) (as of Debian Lenny) segfaults when asked to dump a VD
	when the filename is too long (more than 72 characters or so),
	e. g. (NB: this version is also subject to Bug#437098, which was
	closed as of 4.1r4-22.):
