A few lines below this we check whether `mmfile[i].ptr` is `NULL` and
replace it with the empty string if so. So this patch here is basically
a change in behaviour where we now die instead of falling back to the
empty value.
I'm not familiar enough with the code to say whether the old behaviour
is intended or not -- it certainly feels somewhat weird to me. But it
did leave me wondering and could maybe use some explanation.
