Thank you all for the answers, and your pointers to additional info (@Bob: very
useful article )!

According to ARC documentation, out parameter will be changed to auto release
one:
NSError ** error will be auto changed to NSError * __autorelease * error.
So It's expected behavior that crash happens. An article about this here

I wonder if the problem might be that data is an autoreleased object, which
automatically gets dealloc'ed at the end of the autorelease pool (as explained
in the docs). Have you tried replacing
*error = data
with
*error = [data copy]
and seeing what happens?

Xcode 4.5.1, ARC enabled.
I've this C++ member function, for a testing environment (gtest):
NSDictionary* fetchUser(NSNumber* ID, NSError** error)
{
id user = nil;
//@autoreleasepool // crashes when @autoreleasepool is enabled
{
id data = ...; // response body of a HTTP Res
Well, I didn¹t get any response as to how to make that beast ARC compliant,
so I did something else. Keeping the same basic undo architecture as used
in Sketch, I created my own version of NSMutableDictionary, albeit much
simplified, containing only what I needed. Sometimes the standard classes
