Suggested by Jakub: - if (!len || TREE_CODE (len) != INTEGER_CST) + if (!len + || (TREE_CODE (len) != INTEGER_CST + && !gfc_is_simply_contiguous (expr, false))) Though, one needs to be careful that one zeros the right spot (maybe already taken care of): a(5:) = 0 Additionally, one could do the same for arrays which are contiguous but have a descriptor - for which one has to calculate the size manually (as "len" == NULL). At least after memset/memcpy middle-end fixes, the change should be profitable. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41137
