object raising

It is perfectly correct grammar but may not occur very often, and thus may sound unnatural to native ears. An infinitive (to feel) can be used as the subject.

Thank you for the answer.
But still I am not fully convinced of its correctness.
As clearly seen in 1, the operation applied to both 1,2 is object raising.
And sentence 1 is no doubt grammatical because the subject noun(this problem) is in fact the object of the preposition, whose original version is It is hard to deal with this problem.
