In the code you provide, the first line allocates a brand new
dictionary and assigns it to vAttributes.
In the next line, you reassign vAttributes to the contents of your
iVar dictionary. Nothing points to that alloc'd dictionary in the
first line anymore.
Since vAttributes now points to an autoreleased dictionary, attempting
to release it will cause a crash.

Hi!
I'm a rookie with Cocoa development, please excuse if this question
is stupid, but I'm struck with memory management (an even Aaron's
book doesn't help me):
In a method I use a (temporary) dictionary "vAttributes" to read an
object from an instance variable "vColors" (a dictionary, too):
It is my understanding, that after the "alloc" message
"vAttributes"' retain count is 1 and as I use it in the return
statement, a "release" out of question. So "vAttributes" should
receive an "autorelease" message before the return statement to
avoid an object leak, but than the application crashes after the
first invokation of this method.
... where am I wrong?
