Hi,

Urm ... better "3 rather than 1":
(char *) entry < (char *) sua + sua_size - 3 && entry->len > 0
The memory fault by entry->len will appear if
entry >= sua + sua_size - 2
(Only good i did not submit a patch attempt.
Why is that "- 1" present anyways ? Shall it ensure the presence of
entry->type ?)
Have a nice day :)
