There are two ways that a diesel engine can be damaged by using gasoline.
The first is that "gasoline" has a completely different burn profile form diesel or any other fuel of that nature. The gasoline would be injected and start burning far sooner than a heavy fuel. This will cause extremely high cylinder pressures and higher temperatures.
The second is that the high pressure injection equipment that diesel engines use needs the fuel to lubricate and cool it. Typical gasoline type motorfuels do not do this well at all and the injection equipment will not last very long. This is less true today than it once was. The new low sulfur diesel fuels also lack the lubricity that was once available. That is why a lot of old truck were for sale "cheap" in the late 90's.
