The same name for BasicBlock

[liushengahn]

Hello, I've encountered an issue with basic block renaming in the latest version of AFLGo. I noticed the previous issue #116 regarding this matter, and I think the fix applied should have addressed it. However, I'm still experiencing problems with basic block renaming when running it. I would appreciate your assistance. Thank you.

  int i = 0;

  if (arr[i++] == 'c') return 0;

  if (arr[i++] == 's') return 6;

  if (*(int *)arr != 0xdeadbeef) return 0;

  // Can we trigger this code?
  return (int)(20 / t1);
}

int main(int argc, char *argv[]) {
  // open file
  FILE *f = fopen(argv[1], "rb");

  // get file size
  fseek(f, 0, SEEK_END);
  long fsize = ftell(f);

  // read file contents
  fseek(f, 0, SEEK_SET);
  char *string = malloc(fsize + 1);
  fread(string, 1, fsize, f);
  fclose(f);

  // pass string to foo
  int retval = foo(string, argc - 2);

  free(string);
  return retval;
