The simplifier is often unable to prove easy conclusions, because conditions
given als assert, precondition, and postcondition occur as a single
conclusion.

Example:
C1: res__1 >= buf__first and res__1 <= buf__last and (res__1 >= 0 and res__1
	  <= 0) -> res__1 >= buf__first and res__1 <= buf__last .

Or do I misinterpret this line containing an implication?
Should the simplifier not able to handle this by transfering the frist part
to the hypothis?
