The same commands evaluated with PV-Wave (6.21, Solaris 2.6) gives

% Program caused arithmetic error: Floating divide by 0
% Program caused arithmetic error: Floating underflow
% Program caused arithmetic error: Floating illegal operand
% Detected at $MAIN$ (LONG).
print,b
1343554297

While I don't understand the "divide by 0" error at least there is some error
messge. Is this due to the wonderful world of IEEE numerics?
