[Chameleon] Ugly, how to find reason for random chrashes in Chameleon/PHP/NTDLL.dll

[Paul Spencer]

yikes.  Never seen this, nor heard of it until now.  Of course, I'm on 
linux so that's not particularly startling ;)

I personally suspect your mapserver build.  Can you try it with a 
different version (i.e. a 4.4.2 version)?  One without the Oracle drivers?
