Between 1989 and 2011 the behavior was either always undefined or potentially undefined, depending on when, on what data types are involved, on some implementation-specific choices, and on how one reads some passages in the C standard that unfortunately were not written as clearly as they might have been. Between 1978 and 1989, the defining document for C was K&R's "The C Programming Language." K&R doesn't have a notion of undefined behavior; but, neither does it give a definition of what happens in such cases. I think it's fair to say that during this time period the behavior was "not defined", as opposed to being specifically "undefined behavior". K&R is written in an informal style, and is meant to be read as such. Between 1972 and 1978 Unix was not available to the general public, and I think for all practical purposes neither was C. Also AFAIAA there was no recognized defining document for C during that time. IIRC there were some papers written about C before 1978, but nothing like a real language manual. So the answer seems to be either that the question doesn't make sense or that everything is "undefined behavior" because there is no language manual that defines it. I think the key point is that, TTBOMK, nothing has been written to exclude the possibility of arbitrary (aka "undefined") behavior when reading uninitialized memory, perhaps not counting some special cases such as reading via type unsigned char.
