Test currently fails with gnat2goto raising:
SYSTEM.ASSERTIONS.ASSERT_FAILURE : failed precondition from ireps.ads:1875
gnat2goto fails with above precondition failure when translating UKNI/main.adb line 247 which calls a procedure with an enumeration out parameter. This small test program replicates the same fault.
The problem seems to lie in gnat2goto driver/tree_walk.adb procedure Handle_Parameter. The function Wrap_Argument is called with a parameter obtained from the call of the function Handle_Enum_Symbol_Members which appears to return the wrong sort of Irep for the function Make_Address_Of called by Wrap_Argument.
