123 | # I tried compiling with DBM support and sure enough things locked up |
124 | # just as advertised. Checking into it, I found that the lockup was |
125 | # during the call to dbm_open. Not *in* dbm_open -- but between the call |
126 | # to and the jump into. |

128 | # To make a long story short, making sure that the *.a and *.sa pairs of |

130 | # were perfectly in sync took care of it. |
