A Cygwin user reported a crash as in the subject. I traced it to line
468 of info/infokey.c, in which there is a reference to
function_doc_array[a] with a == A_INVALID:
ke.value.function = &function_doc_array[a];
As a result, ke.value.function contains garbage. The following patch
appears to fix the problem in very limited testing:
