non-incremental/QF_BV/brummayerbiere2/smulov4bw0128.smt2 

We try to verify a verification condition for a signed multiplication
overflow detection unit, which is described in
"Combined Unsigned and Two's Complement Saturating Multipliers"
by M. Schulte et al.

Let n be the bit-width, which is even.
We try to verify the following.
If the n/2 most significant bits of the operands are zero, then
the overflow detection unit must not yield an overflow.
Obviously, this is an invalid verification condition
as for example 0011 * 0011 = 1001 overflows in the signed case, which
is correctly detected by the unit.

Bit-width: 128
