was getting a crash as listed below trying to use this and i traced it down to fact there was no dictionary installed
the code around where it crashed should be
speller, err = aspell.NewSpeller(map[string]string{
"lang": "en_US",
})
if err != nil {
fmt.Errorf("Error: %s", err.Error())
*fakeWords = false
}
defer speller.Delete()

so even with the error check its doing the below

Can second that. When using with unknown language:

func Example() {
	opts := map[string]string{
		"lang": "xx_XX",
	}

	_, _ = NewSpeller(opts)
	defer speller.Delete()
// ...
}

It crashes with SIGABRT (seemingly on freeing unallocated probErr although its code is 0 and we shouldn't get there at all 🤔):
