[Not really OT] Crowdstrike Analysis: It was a NULL pointer from the memory unsafe C++ language.

[Walter Bright]

I occasionally peruse lists of software bugs that are sources of security 
vulnerabilities. The #1 issue, by far, is always array out of bounds errors. 
Null pointer seg faults don't even make the list - because they are not security 
vulnerabilities.

D nails the array overflow prevention.
