I got the same problem with perl 3.0 PL.28 on SUN-Sparc (4.0.3) and
VaxStation II (Ultrix 3.1).
A work around is also a dummy assignment
	$DBM{'dummy'} = 'dummy';
previos to the `dbmopen(DBM3, ...);' (important, if the database shall
not be changed by the dummy entry).

Additionally, I found the following problems with ndbm associative
arrays:
- I cannot read (!!!) ndbm associative arrays if I do not have also
  write access (contrary to the manual).
  This problem did not appear in patch level 18 and before.
- `Configure' defines both
	d_ndbm='define'
	d_odbm='define'
  The problem also appeared in previous patch levels.
- ndbm-arrays cannot be set by the construct
	%DBMarray = (key1, val1, key2, val2 ...)
