Hi,
For this formula:

(set-option :smt.threads 2)
(assert (forall ((a Int) (b Int)) 
(exists ((x Int)) (and (< a (* 20 x)) (< (* 20 x) b))))) 
(apply qe)


Z3 debug branch throws out an assertion violation:

ASSERTION VIOLATION
File: ../src/qe/qe.cpp
Line: 1764
l_false != m_solver.check()
(C)ontinue, (A)bort, (S)top, (T)hrow exception, Invoke (G)DB

OS: Ubuntu 18.04
