Re: Re: Again, Segfault with Aolserver, PHP, SquirrelMail

have you run AOLserver under GDB yet to find out where it is segfaulting?

Thanks. The problem seems to be that in the 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. Here is the relevant output from gdb: [New Thread 6151 (LWP 26839)] Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 6151 (LWP 26839)] 0x400afdd3 in canonicalize (
