nullptr NULL denial of service attacks

[coinhubs]

There's one constant source of crashes, SEGV due to NULL pointer de-references in APIs. They are literally everywhere. eg glibc

#include <stdio.h>
int main()
{
puts(NULL);
return 0;
}

C11 had Annex K functions which avoid many crashes, but annex K has not been adopted widely.

Hi Can you please mention which branch and which code is causing this issue so that I can understand it better and try resolving the issue?

All branches. It's easy to reproduce on all computers. Why don't you start there?
