Hi,

I am getting segment violation on following C code being called from C++ routine, 
when compiled on SunOS 4.1.3. 

	typedef unsigned char cblock[8];

	void func(key) 
	register cblock key;
	{
    		int i;
    		for (i=0; i<sizeof(cblock); i++) 
      		{
---------->		key[i] &= 0xfe;
			key[i] |= 1^parity_char(key[i]);
      		}
  
    		return;
	}

I get segmentation violation at index 1. 

I would greatly appreciate, any help as to why this error occurs. Thanks in advance.
