Bug #82875 Crash at rand()

Description:
I get random crashes of MySQLWorkbench.  I get this same issue on my Ubuntu Machine, Vista, Windows 7 and my Windows 10 machine. This happens very frequently, and it doesn't seem to be any one action, but in general when the system is querying.  The mysql server version varies, but appears to happen on all versions of MySQL (anything from v5.1+ to MariaDB)

I do have dev tools installed on these machines (Visual Studio is on all but my Ubuntu machine).

How to repeat:
Happens when filtering to DB, setting default DB or running queries on the DB.
