title: C creating a struct array beyond certain size causes a crash
body: <p>Hi all I am really new to C (just started this week), and want to make sure that I am not looking down the wrong rabbit home and hoping to perhaps get pointed to the right rabbit hole.</p>
  
  <p>I create a struct:</p>
  
  <pre><code>#define MAX 64
  #define ARRAY_SIZE 2048
  
  struct object {
      int q, c, p;
      char name[MAX]; //Stores string up to 63 characters
      char arr[ARRAY_SIZE][MAX]; // Creates an array of 2048 cells with string of length 63 max
  };
  
  int main(){
  ...
  ...
  int variable = 30;
  struct object l[variable]; //This is where the crash happens. But only when either variable is too large (for instance works on 15 just fine, but anything over 20 it crashes), or when Array_SIZE is too larger, for instance works fine with 1024 but 2048 crashes.
  ...
  ...
  }
  </code></pre>
  
  <p>The error I get on crash is the following: <strong>Process returned -1073741571 (0xC00000FD)</strong> in the cmd window. And the following in the debugger in the IDE:
  <strong>Program received signal SIGSEGV, Segmentation fault.
  [Inferior 1 (process 12120) exited with code 030000000375]</strong></p>
  
  <p>Am I doing something obviously wrong with how I declare an array of structs? Why would large numbers not work but lower numebrs work?</p>
  
  <p>Does the above error indicate I am accessing something out of bounds somewhere? Ive been up and down the code and cant seem to find any reason why larger numbers dont work and lower ones do. My memory footprint doesnt seem to be the issue, just a few megs of memory.</p>
  
  <p>I need help with what to look for (I cant find any instances of accessing anything out of bounds, so I get the feeling Im not chasing the right rabbit and need to look for something else)? Or maybe Im doing something illegal for C without knowing it?</p>
