This stops sparse from issuing the error message "error: cannot size expression" for code like: static _Bool boolarray[] = { 0, 1, }; static int n = sizeof(boolarray); The fix consists of using array_element_offset() for calculating the size of unsized arrays, like it is done elsewhere for sized ones.
