this doesn't work for me. I followed your instruction + made composer update.
Anyway, I get a error (that I expect), but not any memory corruptions.
Error: Cannot use Drupal\Component\Utility\String as String because 'String' is a special
class name in ...
I probably need some branch of drupal adopted for PHP7.
Also, do you use any external extension (e.g. xdebug)?

Not exactly sure what you need.
You need to get drupal and drush:
git clone http://git.drupal.org/project/drupal.git
git clone https://github.com/drush-ops/drush.git
cd drupal
gdb --args '/path/to/php7' '../drush/drush.php'
'--db-url=mysql://user:pass@localhost/db' 'si' '-y'
'standard' '-v' '-d'
Update the path to php7 and use a valid mysql username/password and that should install drupal
(which takes a while... ) and at the end, it crashes with the mentioned segfault.

I didn't get how to reproduce this.
Please provide a detailed instruction: what to download, which commands to run, etc.

https://gist.github.com/Berdir/f93e56c8a2643501ce51
has a more up to date debug output now, which shows which object is causing the crash, based on
instructions from @ircmaxell

Description:
------------
This is part of our efforts to get Drupal 8 green on PHP 7, see https://www.drupal.org/node/2454439.
I've been trying to test with the latest PHP 7 build, but I'm now getting a lot of
segfaults during the installer and running any web test.
You can see the backtrace and code where it happens here: https://gist.githubusercontent.com/Berdir/f93e56c8a2643501ce51/raw/653fa8fea95d322f9f7836838177951db7fe57db/gistfile1.txt
I'll try to bisect this down to a certain commit, but I had troubles the last time I tried to
do something like that.
Test script:
---------------
To debug, get drupal and drush (from https://github.com/drush-ops/drush), then:
gdb --args '/path/to/php7' '/path/to/drush.php'
'--db-url=mysql://user:pass@localhost/db' 'si' '-y'
'standard' '-v' '-d'
