There are 2 potential reasons:
1. Session is timed out server side before user submits the form. Either by
normal PHP session cleanup logic or server based cron job cleaner (Debian's
sessionclean you naughty boy!, see /etc/cron.d/php ) This is a thing the
maintainer of the web server has to take care.
2. The $_SESSION must be able to handle multiple browser tabs:
Instead $_SESSION['answer'] use
$_SESSION['form'][$formtoken]['captcha']
or
$_SESSION['report'][$formtoken]['captcha']
$formtoken can either be random generated for each form loaded (session file
storage grows with each page load)
or be reused until the captcha was solved for the $formtoken. (
The forms could contain the formtoken as
<input type="hidden" name="formtoken" value="<?= $formtoken ?>"/>
Or the captcha only needs to be solved once for a user session and all
following form submits do not need solve annoying captchas.

No, the issue has not been fixed. petk's analysis[1] is spot on.

I am under the impression that this has been fixed.

Thank you petk. Your description brings me as many questions as it answers
though. I suggest you explain your decision on your blog, or post an
explanation to a PHP mailing list.
Thank you peehaa

I will have a look in the (relatively) short term to see if I can repro it too
and can implement a quick fix for it where I find the problem.
