On my system, it crashes with any dbm file, even one with no
entries.

problem using a ndbm database that I have.

Description:
------------
This program prints Resource handle #5, and then crashes.
It works OK in 4.2.2, crashes in a version of 4.3.0 I had
lying around. It crashes in the Apache module, which is
where I first noticed it.
There also seems to be a change since 4.2 that it used to append .db to
the file name but doesn't any more.
It's compiled --with-mysql --with-apxs --with-ndbm
(I know that ndbm is old and tired, but it's distributed
with BSD/OS and I have a lot of existing ndbm files that
I'm using.)
Reproduce code:
---------------
$a = dba_popen("test.db", "r", "ndbm");
print "handle is $a\n"; // prints Resource #5
$k = dba_firstkey($a);
print "key is $k\n"; // segfaults, see trace below
Expected result:
----------------
should print first key in db file
Actual result:
--------------
