There is a program written in C++ that runs under debian 8.
The problem is that the program crashes at first glance completely randomly, it can work for a day and crash, it can work for 15 minutes and crash, or it can perform its functions and not crash at all.
How to identify the cause of such a fall, what means to use?
PS Imitation of user actions does not work. More than 50% of the RAM is always free.

Enable core dump (ulimit -c unlimited), collect and analyze dumps in the debugger.
