I am unable to complete the installation because of PHP Notices. Past the initial screen that allows me to choose an installation profile, my screen is filled with a lot of this:

Notice: Constant MARK_READ already defined in /Sites/drupal-7.x-dev/includes/theme.inc on line 24 Notice: Constant MARK_NEW already defined in /Sites/drupal-7.x-dev/includes/theme.inc on line 29 Notice: Constant MARK_UPDATED already defined in /Sites/drupal-7.x-dev/includes/theme.inc on line 34 ...

Is this a known issue? I couldn't find any other issues reporting this.

..just ran into this aswell, seems to be called by strange APC behaviour if apc.include_once_override=1 is set (will presumably become unnecessary with PHP5.3 anyways). If indeed you have APC enabled with this, try setting apc.stat_ctime=1 aswell and relaod your apache conf. See http://pecl.php.net/bugs/bug.php?id=15356 for reference...

Thanks eMPee584, yes I think that this could be a bug with APC, I think that it was causing theme.inc to be included twice. Setting apc.stat_ctime=1 did not solve the issue, but turning off APC completely did get ride of the warnings, though I was still seeing this:

Warning: Invalid argument supplied for foreach() in /Users/user/Sites/drupal-7.x-dev/includes/database/database.inc on line 1430 Warning: Cannot modify header information - headers already sent by (output started at /Users/user/Sites/drupal-7.x-dev/includes/database/database.inc:1430) in /Users/user/Sites/drupal-7.x-dev/includes/bootstrap.inc on line 1003 ...

A separate issue?

Edit: see #671366: Installer is broken for more about this warning.

I think that last warning was caused by the absence of a settings.php file, a separate issue.

So is there anything that we can do about this? Or is this purely an APC bug?

According to http://pecl.php.net/bugs/bug.php?id=15356, include_once_override is an experimental feature with known issues, so I supposed that the solution is to turn off this feature.

apc.include_once_override=0
