in first test, app crashed and no idea to try-catch it.


You tried to write to an address which was not allocated as writable memory to your application.

The operating system detects that and issues a system exception for the application.

in second test, GetName() is called properly without any problem (funny).


You are calling a method via static binding. Static binding in the code of your application is normal for your application.

The method itself is in the code space. Thus legal as well.

The method doesn't address any illegal addresses so no problem.

> how to detect, catch or provent crash from invalid pointers as tests above, or other common cases?

Find or buy libraries which detect memory problems, of many types.
Build your application with those.
Then run your application testing ALL of the code paths (there are other tools that track that.)
The library will tell you about improper memory usage.
