Runtime error: Index out of range

[Masquerade0097]

I'm getting the following error when trying to run a package that uses go-forceexport. Here is the error log -

panic: runtime error: index out of range [66428884777697280] with length 15718508

GetFunc‘s principle is to traverse the symbol table.The get func has the bug, the ftab.funcoff maybe bigger than pclntable please add

if int(ftab.funcoff) >= len(moduleData.pclntable) {
				continue
			}

whole func:

func FindFuncWithName(name string) (uintptr, error) {
	for moduleData := &Firstmoduledata; moduleData != nil; moduleData = moduleData.next {
		for _, ftab := range moduleData.ftab {
			if int(ftab.funcoff) >= len(moduleData.pclntable) {
				continue
			}
			f := (*runtime.Func)(unsafe.Pointer(&moduleData.pclntable[ftab.funcoff]))
			if f.Name() == name {
				return f.Entry(), nil
			}
		}
	}
	return 0, fmt.Errorf("Invalid function name: %s", name)
}
