"/" || "\\" evaluates as as a logical or of two addresses neither of  
which will be zero.  This gives you a result of true (1)

'/' || '\\' evaluates as a logical or of 0x2F and 0x5C.  This also  
gives you a result of true (1)

It seems to me that the ldd #1 makes perfect sense.  That still  
leaves the mystery of the lead code.
