Segmentation fault after upgrading to 1.5.18-1

Hi, yesterday I upgraded my cygwin on Windows XP to the 1.5.18-1 version, and
now the previously installed postmaster (7.4.5-1) doesn't start anymore. It was
working fine before the upgrade.

The environment seems correctly set up:

admin(at)DATA ~
$ env | grep CYGWIN
CYGWIN=server

and the cygserver service is running:

admin(at)DATA ~
$ ps -ef
UID PID PPID TTY STIME COMMAND
admin 776 1 con 19:11:17 /usr/bin/bash
SYSTEM 2936 1 ? 12:06:11 /usr/bin/cygrunsrv
SYSTEM 928 2936 ? 12:06:11 /usr/sbin/cygserver
admin 3624 776 con 12:10:29 /usr/bin/ps

However, when I start postmaster it runs for a few seconds only and then stops.
I upped the log level, and here's the result of starting postmaster manually:

admin(at)DATA ~
$ postmaster -D /var/postgresql/data -i

I tried tinkering with the /etc/cygserver.conf file, but I'm not making any
progress because I don't know exactly what I should change... Any help is
*greatly* appreciated.
