3.4p1: 'buffer_append_space: alloc 10506240 not supported'

[Thomas Quinot]

I have been trying to install 3.4p1 on a number of machines.
Servers on ia64 Linux, i386 Linux and SPARC Solaris are all working
like charms. On the other hand, I am having trouble at least with
HPUX 11, DEC OSF 5.1 and Unixware: on all those systems, sshd bails
out after authentication with an error in buffer_append_space.

Here is the output of sshd -d on the UnixWare machine
(uname -a: "UnixWare sofia 5 7.1.0 i386 x86at SCO UNIX_SVR5")
