--- Comment #3 from Michael Hudson-Doyle <michael.hudson at linaro dot org> --- The problem is that the call to "m.Call" at https://gcc.gnu.org/viewcvs/gcc/trunk/libgo/go/reflect/makefunc.go?revision=212853&view=markup#l133 needs, in this case, to be a call to "m.CallSlice". I don't know how it can know when it needs to do that though.
