Bug #714: pg_dump segfaults when given an invalid command line option

I just tried with current CVS and got:

$ aspg pg_dump --someoptionthatdoesntexist somedb

pg_dump: unrecognized option `--someoptionthatdoesntexist'
Try 'pg_dump --help' for more information.

My guess is that there is something buggy with your libc getopt. Can
someone else reproduce this error?

The lower the number the more severe it is.

Short Description

A core file is left behind.

This is fixed since 7.2.

Sorry but I'm using 7.2.1 and am seeing the problem :).
It didn't occur on the same machine/libs with 7.1.2.
