Description

simplify(or(vBool(), vBool())) produces exception which means RexSimplify tried to assign different values to the instances of ?0.bool0

java.lang.AssertionError: result mismatch: when applied to {?0.bool0=false, ?0.bool0=true}, OR(?0.bool0, ?0.bool0) yielded true, and ?0.bool0 yielded false
