If the function "nop" is made a non-template function (by uncommenting the typedef in line 4, and commenting-out the "template<class T>" prefix in line 7), the obligation reads "goal main_assert: forall i : int. (2 = (2 * i)) -> is_sint32(i) -> (1 = i)", and is proven without problems by Alt-Ergo. ## Attachments - [411.cpp](/uploads/f4d3734df967c73ae7c415efd8c5d1de/411.cpp) - [main_assert_Alt-Ergo.mlw](/uploads/13ed07ef6485c5aa5d0eafa5599fabbf/main_assert_Alt-Ergo.mlw) - [411a.cpp](/uploads/0ffcaa8993e4cb1ec8e78eb5d2774ac2/411a.cpp)
