With 3.3 and 3.2.4 is it still required to turn the plugin Remember me off? What is the technical reason?

I didn't know that, where did you hear that?– jackJoeCommented Apr 24, 2014 at 7:36

It is advice given on forum.joomla.org. See forum.joomla.org/viewtopic.php?f=710&t=825407 as an example.– sovainfoCommented Apr 24, 2014 at 9:41

@jackJoe It's quite common: Fatal error when updating joomla from 3.1.1 to 3.2.2– iliasCommented Apr 24, 2014 at 11:58

Indeed, only that is after the update went wrong. The advice to turn off makes the update succeed, if there are no other problems offcourse. A failed update might leave you in limbo, very difficult to recover from it.– sovainfoCommented Apr 24, 2014 at 13:55

I had that issue on a couple of upgrades 3.1 up and was happy I had a backup and mysql access to stop them being totally locked in white screen crash– tristanbaileyCommented Aug 11, 2014 at 10:56

To answer 'what is the technical reason', I took a look through the tracker and GitHub notes. The issue seems to be two-fold - a failure to delete certain files during the upgrade, and failure to apply certain SQL updates. However, if only affects some and not others. See the bug tracker for additional info.
The general best practice option approach seems to be:
If not already borked...
- Backup!
- Disable
System -> Remember Meplugin - Do the update
- Enable
System -> Remember Meplugin
If borked and no backup...
When the install fails on url /administrator/index.php?option=com_joomlaupdate&task=update.finalise with php error '\plugins\system\remember\remember.php on line 94'
Running \cli\deletefiles.php from the command line then refreshing the /administrator/index.php?option=com_joomlaupdate&task=update.finalise gives FULL SUCCESS
This commit ostensibly fixes the issue, but suggest it's to do with $this->app not being prepopulated by the system. It may also be worth a look if the above fails. Keep in mind this is quite a recent pull request (16th April 2014) and hasn't been approved in the tracker: YMMV.

Amazingly I completely fell into this trap moments ago. The answer definitely works :) Commented May 1, 2014 at 13:54
The problem only appears on certain servers, for reasons I don't yet know exactly. On my servers it works without issues, but a friend had this problem as well.
I have done a PR which I believe will solve the issue, see https://github.com/joomla/joomla-cms/pull/3467. If someone who has this problem can test this patch and see if it fixes the issue, then that would be great :-)
