Higher versions of Golang will crash

[eddielth]

At that time, I was using a higher version of Golang (Version>=1.14)，when this method is executed, an error will be reported and the program will crash. D:\go\pkg\mod\github.com\go-ole\[email protected]\oleutil\oleutil.go

func CallMethod(disp *ole.IDispatch, name string, params ...interface{}) (result *ole.VARIANT, err error) { return disp.InvokeWithOptionalArgs(name, ole.DISPATCH_METHOD, params) }

The panic error such as blows: textual

• textual.color
• textual.number
• textual.random
• textual.weekday Exception 0xc0000005 0x0 0x566a7d10 0x1f51b1d9 PC=0x1f51b1d9
