It appears if you are not using Xcode (mine - 4.5.2), but just a simulator (mine 6.0) that when an application crashes it saves a crash report. To view it, create an application / Utilities / Console and
(1) make sure it shows a list of logs (see the top left of the console to make sure it is not hidden)
(2) in the “DIAGNOSTICS AND USE OF INFORMATION” section there are “User Diagnostic Reports” which, if you open, must have error reports
(3) the area to the right of the console has a log
