Thanks. It is happening when in the PHP statement
include "../src/load_prefs.php";
The relative path is expanded to
/usr/local/aolserver-3.4.2/servers/webmail/pages/squirrelmail-1.2.0-rc2/src/../src/load_prefs.php
instead of:
/usr/local/aolserver-3.4.2/servers/webmail/pages/squirrelmail-1.2.0-rc2/src/load_prefs.php
I.e the ".." is not treated correctly. It seems to be PHP's fault.
here is the relevant output of gdb:
[New Thread 6151 (LWP 26839)]
