I did some searching and found:

It looks like HP-UX has an eight-byte socklen_t and a four-byte int, and
has two different versions of getsockopt(), one which expects a pointer
to int in the last parameter and one which expects a pointer to
socklen_t.  Since we don't do anything in our build system to choose
"X/Open sockets," we probably get the first one.

If you change sockerrlen from socklen_t to int, does it start working?
I'm not sure if we can make a reasonable change to accomodate this if
so, but it would be good to know.  There seems to have been some
confusion among various standards bodies over what type the optlen
parameter should point to.
