Re: Running app with ARC turned off

[Daniel Santos]

I have some test classes that run the code (the main code is a library) and if 
I don’t create an AutoReleasePool object I get warnings like :

autorelease called without pool for object of class … (for example 
GSMutableDictionary)

Does that mean that it is my responsibility to release the object right ? But 
most of the objects in the warnings belong to GNUstep base (which I am using)
