title: What is a segmentation fault on Linux?
body: <p>In Linux:</p>
  
  <p>What is a segmentation fault? I know it crashes programs, but is that some sort of memory leak problem, or something completely unrelated? Also, how do you deal with these?
  Is this typically a problem with the computer set-up, or within the application itself?</p>
  
  <p>Also, does this happen in other OS's as well?</p>
