Is the mistake that they're allocating 1 byte and storing in a pointer to an int which is 4 bytes?

I believe it’s compliant to have malloc(1) return memory that can fit an int.

sizeof(char) is always 1; malloc works based on sizeof.

char is allowed to be anything >= 8 bits wide

int is >= 16 bits.

In theory, you could have char and int both be 16 bits.

Edit: this is why you should always do malloc(n * sizeof(type))

Edit 2: Wikipedia (C data types article) literally states that a platform could theoretically have all int types be 64 bits, for those who doubt me.
