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:
