SSL seg faults with sessions (4.1.0+)

[Anon]

I am having some very weird problems trying to upgrade to php-4.1.0 or 4.1.1 (tried both..)

Sometimes when posting under SSL php seg faults apache when session_start is called.. it's about 30 -40 % of the time..

What's weirder is that i also tested it under a reverse proxy situation where the apache server running php wasn't ssl enabled but was receiving ssl connections from the the load balanced proxy server..

My guess is that some http headers/formatting unique ot http (to do with cookies??) are causing the problem..

I've tested this with apache 1.3.19 & apache 1.3.22, latest mod_ssl for each version respectively..

PHP 4.06 does not exhibit the problem (haven't tried 4.07)

However, in dev i've started using $_GET, POST etc.. so i really would like to get 4.1.0+ working...

OS/wise i've tested it on linux mandrake 7.2 with a 2.4.x kernel, mandrake 8, cobalt os (kernel 2.2.16) & solaris 8.. same problems..

Any thoughts, comments, help would be appreciated..

Cheers,
Tim

Are you using a custom session handler?

There is a problem in PHP 4.1.x - if your custom session_read function returns false or null it will cause a segmentation fault as PHP expects the returned value to be a string. If you force type-convert your return value to a string, this will stop the segfaults.

That did the trick. Thanks!

i'm still a bit confused as to why it only happened under SSL....
