Synopsis: Wrong error reported on generic class with formal constrained twice by same class
Description
For a class class TEST2 [G -> {ANY, ANY} create default_create end] the compiler reports a VGCC(1) error and a VTCG error. It should report a VTGC(3) error since that is the real source of the problem and adding a rename for `default_create' in one of the two constraining types allows the class to compile. Note also that if the constraint is instead class TEST2 [G -> {ANY, TEST1} create default_create end] then the compiler correctly reports VTGC(3). Added eweasel test multicon053 for this bug.
To Reproduce
Run eweasel test multicon053.
