When trying the following, dates near or before 1 Jan 1970 cause segfaults.

[1]> (encode-universal-time 0 0 0 1 1 2009)

The closest I got was about here:

2208988800
[7]> (encode-universal-time 0 30 12 1 1 1970)

It seems anything previous to that also segfaults.

Not sure if time zone/daylight savings is important, but I'm at NZST +12hrs.

An older cygwin version (own build) of clisp-2.41 runs all the above just fine.
