Hi Rudy, I have provided info from several places at the request of one of your colleagues.
I’m not really willing to try and reproduce the crashes under OSX because one of them shut off my computer as if the power cable had been pulled. That can damage the hard drive so I won’t be using OSX version of UE4 anymore, (Not unless you want to send me a computer specifically for testing! 
)
So far, I’ve only had one crash under Windows and the crash reporter worked fine for that so I think there is not too much of an issue there.
I think that one can easily be reproduced since it happened under OSX and also under Windows. Here are the details from that one. https://answers.unrealengine.com/questions/144556/bug-reportcrash-log-submit.html
