I'm not an objective C expert (or even amateur) -- but it looks to me like your
use inside the function call is not setting anything in the object but appears
to be a cast.
So your old success would completely depend on the behavior of the memory
allocator and garbage collector and how it reuses things.
Isn't this:
sqlite3_bind_text(statement, 3, [self.lemmaRicerca
cStringUsingEncoding:NSUTF8StringEncoding], [self.lemmaRicerca
lengthOfBytesUsingEncoding:NSUTF8StringEncoding], SQLITE_STATIC);
Saying "return self.lemmaRicerca as a cString..." and not "set
self.lemmaRicerca..."
So it would be out-of-scope outside the function call as you can't reference
the UTF8 format again, correct?

I tried and it did indeed fix the issue. Since I'm not deallocating any
memory however this means that the garbage collector is. This conflicts
with the Apple documentation, that states that the buffer provided by
NSString objects should persist until the owner object itself is
deallocated... This apparently is not the case in Snow Leopard, or they
have changed something else that broke it.
Thanks for the help!
