I am sure this is a misinterpretation. The code just does not work that way.
Something you have not notices changed between those versions of your code.
When you say "giving a problem", I assume you mean the option does not take
effect. The most common cause is a misunderstanding of the mechanism. If you
call a function to set something, but subsequently call
SetFromOptions(), it will
be overridden by command line arguments

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which
their experiments lead.
