Question

My simplified code looks like something below:

 char decrypted[64] = "P@ssw0rd                ";
 int realsize = 8;
  realloc(decrypted, realsize);

  char *dec2 = (char *) malloc(realsize+1); // Exe crashes at this point

I am guessing it has to do with char *dec2 , but this only crashes Win XP for some reason.

Answer 1

You cannot realloc() what hasn’t been allocated with malloc() or calloc() or realloc().
