I had the same problem, I used a couple different ways to try to figure out the cause of the crash.
One way is to run Nsight and let the application crash inside it, save the dump file and inspect it with windbg.exe …
Another way is to use Nvidia Aftermath, download and documentation are on this site …

Another way, although not necessarily helpful with the crash itself, can give you the execution steps of the application so you might get some idea of what it was doing when it crashed is glintercept.
Good luck.
