BUG #1897: dmalloc memory error on PQconnectdb
The following bug has been logged online:
Bug reference: 1897
Logged by: Wade Hampton
Email address: wade.hampton@nsc1.net
PostgreSQL version: 8.0.3-1
Operating system: Fedora Core 4
Description: dmalloc memory error on PQconnectdb
Details:
I have a multithreaded application using Postgresql and am testing for
memory leaks. I compiled and linked with dmallocth. My PGconnect() is now
causing a dmalloc abort. The error appears to be a calloc of 0 elements of
40 bytes in libkrb5, called from libpq.
The connection is to: hostaddr = 127.0.0.1 dbname = mydb
The same code with dmalloc works fine with Fedora Core 2.0, Postgresql
7.4.7-3.
There was a report of a similar problem in earlier versions:

hi,
i have a problem when i run the initdb file, do you know anything?
bash-2.05b$ /usr/lib/postgresql/bin/initdb -D /var/lib/pgsql/data
The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.
The database cluster will be initialized with locale C.

(1) Why is that a bug? calloc of 0 elements is explicitly allowed by
the Single Unix Spec:
http://www.opengroup.org/onlinepubs/007908799/xsh/calloc.html
(2) If you do think it's a bug, why are you complaining to us rather
than to the Kerberos people?

This reminded me a bug that was fixed in 7.4.2. Are you using 7.4 or
7.4.1?

What PG version is this exactly, what platform are you running it on,
and what locale environment are you running initdb in? (For the last
question, show the output of "locale", or if you don't have that
program then "env | grep ^L".)
