From: Ruediger Meier <ruediger.meier@xxxxxxxxxxx>
fdisk -l could crash randomly. Only seen on some i586 systems with
certain exotic compiler options.
The problem was that this item is later used in
function fdisk_reset_labelitem() like this:
if (item.type == 's')
free(li->data.str);
This may crash if item is randomly initialited.
