I'm trying to install Aolserver 3.4.2 and PHP 4.0.6, but on the statement
include "../src/load_prefs.php";
The server segfaults. Perhaps the server shouldn't crash but the problem is
that ".." is being interpreted as:
/usr/local/aolserver-3.4.2/servers/webmail/pages/squirrelmail-1.2.0-rc2/src/../src/load_prefs.php
rather than:
/usr/local/aolserver-3.4.2/servers/webmail/pages/squirrelmail-1.2.0-rc2/src/load_prefs.php
I never had a problem with Aolserver 3.0 + PHP 4.0.6 on a machine running
RedHat 6.2. This is cropping up with RedHat 7.2 + PHP 4.0.6 using either
Aolserver 3.4.2 or Aolserver 3.0. Is there some problem between RedHat 7.2
and PHP 4.0.6 (glibc maybe? I'm using glib-2.2.4-19).
Here is the backtrace with Aolserver 3.4.2:
