sv command does not work

[slugrustle]

The sv command, even the one copied from the readme, does not appear to function. The following occurs on my system:

Enter a command: sv 100000011000000000000000000000000000
16: 111111111111111111111111111111111111spot▒╩Üc▄ε

The below modification to the code appears to fix things:

    else if(memcmp(buff,"sv",2) == 0)
    { 
		char instruction_string[WORD_SIZE];
		memset(instruction_string, 0, WORD_SIZE);
		if (read_size > 3)
		        memcpy(instruction_string, buff+3, WORD_SIZE < read_size-3 ? WORD_SIZE : read_size-3);
	  
		int *byte_value;
		byte_value = (int*) malloc(WORD_SIZE*sizeof(int));
		byte_value_from_string(instruction_string,byte_value,WORD_SIZE);
		for(int i=0; i<WORD_SIZE; i++)
			Machine_Memory[pc.current_address][i] = byte_value[i];

		set_address(&pc,pc.current_address,Machine_Memory);
		free(byte_value);
		char* memory_value = (char*) malloc(WORD_SIZE);
		byte_value_to_string(Machine_Memory[pc.current_address], memory_value, WORD_SIZE);
		fprintf(stdout, "%d: %s\n",pc.current_address, memory_value);
		free(memory_value);
    }
