  18. <snip>
  19. MD: You must allocate more memory because these are the bytes to be allocated:
  20. MD:     solution_array = (char **) malloc(size * sizeof(char **));
  21. MD:                                           ^^^^^^^^^^^^^^^^^^  
  22.  
  23. I have not followed the context, but this statement cannot be desired!
  24.  
  25. First, loose the cast and #include <stdlib.h>.
  26.  
  27. Next write it as
  28.   solution_array = malloc(size * sizeof *solution_array)
  29.  
  30. <snip>
  31. MD: here too:
  32. MD:            solution_array[row] = (char *) malloc(size * sizeof(char *));
  33. MD:                                                      ^^^^^^^^^^^^^^^^^
  34.  
  35. Here too:
  36.  
  37. solution_array[row] = malloc(size * sizeof *solution_array[row]);

  39. Cheers
