It is just the difference in compiler flags. You would have to look at the
compiler documentation.

If my program works fine in the debugging version, does it mean that I will

One trouble is that despite this system, anyone who reads journals widely
and critically is forced to realize that there are scarcely any bars to
eventual
publication. There seems to be no study too fragmented, no hypothesis too
trivial, no literature citation too biased or too egotistical, no design too
warped, no methodology too bungled, no presentation of results too
inaccurate, too obscure, and too contradictory, no analysis too
self-serving,
no argument too circular, no conclusions too trifling or too unjustified,
and
no grammar and syntax too offensive for a paper to end up in print. --
