That's really very bizarre.  First, AFAIK, (1ULL << 36) should be just as
valid as what I recommended.  The longer form that I used is, I thought,
out of personal preference (something I probably should've noted in the
previous message, sorry) and entirely unnecessary.  Second, your compiler
should at least warn about doing

  sprintf(buf, "... %lld ...", ..., (1ULL << 36), ...);

since you're providing an unsigned value for a signed conversion.  What
compiler are you using?  Are all the warnings turned on?
