That's line 273 of ndarray.cxx:

NDArray NDArray::CopyTo(NDArray * other) const {
static FunctionHandle func_handle;
MXGetFunction("copyto", &func_handle);
CHECK_EQ(MXFuncInvoke(func_handle, &blob_ptr->handle_, nullptr,
&other->blob_ptr_->handle_),
0); // THIS FAILS
return *other;
}

Fixed by h2oai/h2o-3@7897cb0, not yet clear why.
