We are using a custom version of the Crash Report Client (CRC) to hook up additional bug reporting features related to crashes that might happen during development.
Into the FCrashReportClient constructor we retrieve some data from the crashed app by retrieving it through FGenericCrashContext::GetCachedSessionContext(). This allows to access the internal static NCached::Session field.
We noticed that in our internal QA development build, those variables were empty.
So for instance when debugging the CRC itself we can see that FGenericCrashContext::GetCachedSessionContext().BuildConfigurationName is an empty string, and so on.
And yet we can see that the XML file where all crash properties have been serialised is full of meaningful data. It looks as if the static data had been used once and then wiped out.
We do not have this issue with locally built Development (or Development Editor) executables, only those built by our build machine for QA purpose.
What could be the reason for this?
