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

Menno Smits (menno@oxcoda.com) reports a bug with a severity of 3
The lower the number the more severe it is.

Short Description
pg_dump segfaults when given an invalid command line option

Long Description
pg_dump crashes with a segmentation fault and dumps core when given an invalid command line option.

Example:
$ pg_dump --someoptionthatdoesntexist somedb
Segmentation fault (core dumped)

A core file is left behind. 

Version information:
Postgresql version 7.2.1 on a Redhat 6.2 based system.
Postgresql installed from RPMS built from the official SRPMS.
(ie. rpm --rebuild postgresql-7.2.1-2PGDG.src.rpm)

Sample Code


No file was uploaded with this report

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?

This is fixed since 7.2.

    Fix pg_dump help option alignment.

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.
