Hi, I've been trying to setup Menalto Gallery and after I got through
entire setup
of a fresh installation (to verify php, MSSQL, IIS were working fine), I
pointed
the gallery to my existing database and flat files. Because my data
came from an
older version of the Gallery, it invokes upgrade wizard which dies every
single
time on step 2. I've created a crash dump with adplus and it appears to
be
exactly the same bug as what's reported here.
This is 100% repeatable on my machine. I'm using PHP 5.3.2 with Windows
2008
Server R2, IIS7 and MSSQL 2008 R2. I've also been able to get past the
crash by
adding "zend.enable_gc = Off" to php.ini

I'm not able to reproduce it. May be it's already fixed. Could you
verify?

I gave it a try with
zend.enable_gc = Off
The segmentation fault no longer occurs

Looks like a gc issue. Confirm by setting:
zend.enable_gc = Off
in your php.ini
