Description:
------------
Version tested with 5.4, 5.5.13, 5.5.16

I use symfony and doctrine.
In sometime doctrine creates hash map array with spl_object_hash for proxy object "Foo"
Then, there is my buiseness logic, and in sometime I create new object "Bar" (not Customer), which spl_object_hash is in doctrine hash array. I marked that, when my object "Bar" cant persist in my database, because doctrine find hash from other object "Foo" and think object is managed.

I noticed, that any object created before "Bar" become with the same object hash, and Bar has different hash.
So, only order of init objects are influence to object hash.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

spl_object_hash() only guarantees uniqueness for objects that still exist in memory, but it doesn't sound like that's the issue here.
