Re: [AOLSERVER] Again, Segfault with Aolserver, PHP, SquirrelMail
Scott, I've been using this Aolserver 3.0 + PHP 4.0.6 for over a year with no problem -- this is new (mis)behavior. In what I'm trying to setup now, the PHP version is the same, but I'm trying to use new versions of Aolserver (3.4.2) and RedHat (7.2, old server has 6.2). I cannot think of any way that Aolserver is causing this problem for PHP, though. At 06:59 PM 11/26/2001 -0600, you wrote: Hi Sean, Is this something you can fix on your own? It's possible that the PHP module for AOLserver is doing this (i.e. it's building a path without checking for relative paths); I'm not sure as I've never used the module or PHP. /s.

I did (tsrm_virtual_cwd.c, for instance, is part of PHP) but but there is no file called canonicalize.c on my system. Is it built into gcc or something? It seems to be part of stdlib.

Send that output. It may help us.

[AOLSERVER] Again, Segfault with Aolserver, PHP, SquirrelMail
Hello, No one seems to want to touch this, not on the Aolserver list, not on the PHP list, not on the SquirrelMail list. However, I'm going to try again. On a server running RedHat Linux 7.2, I've got Aolserver 3.4.2 compiled and working fine, and PHP 4.0.6 compiled as a module and working fine except when it segfaults. It occurs consistently when loading SquirrelMail's (1.2.0-rc2) src/right_main.php, though I think the problem is really in the called function sqi_mailbox_list from functions/imap_mailbox.php. Exactly what the server is trying to do when it crashes I haven't yet figured out. The PHP source distribution warns about trouble with multi-threaded servers, but the suggested workaround, removing a line of code, refers to a line that no longer appears to be in the code anyway. Has anyone had a similar problem? Can anyone help me solve this problem or debug it more accurately? I currently have Aolserver 3.0, SquirrelMail 1.0.6, and PHP 4.0.6 running with no problems on another server under RedHat 6.2 (I'm trying to migrate our webmail onto a new machine) so this is very frustrating. Thanks. Sean Redmond Brooklyn Museum of Art
