Well.. on certain compilers ( & coupled with link editors on that platform), it's possible to run code that could run into dereferencing 0x0 & not crash. A good example would be HP-UX. Frankly, any occurance of this scenario would be due to bad programming.
Since we are porting code from HP-UX to linux, there are a lot of such instances. Instead of going thro the entire source code for a potential crash, i was wondering if there was an easy way out... Just like HP-UX. I'm aware that on Solaris you could link email@example.com
that fixes this. But i cant seem to find anything for linux.
