title: segmentation fault after main returns
body: <p>I have a long program in c over Linux, that gives me segmentation fault after main returns.
  Its a long program, so I cant post it. So can you help me what can make such error?</p>
  
  <p>Thank You.</p>
  
  <p>Wow, Those answers came really fast. Thank you all.
  I think i worked it out, i forgot to malloc a string and used it as buffer.
  Now that I've malloced it, it does not signal me with a segmentation fault.</p>
  
  <p>Once again, thank you all.</p>
