This\nis true on x86_64, but very much not true on i386.\n\nThese assumptions can cause the end condition to malfunction, leading\nto a 'short' clone. Guess what happens when the user mapping has a\nshort copy of the entry text?\n\nUse the correct increment form for addr to avoid alignment\nassumptions."
