Can't compile latest PCL on AKCL 1.122

["lgm@att.att.com"@ihlpf.att.com]

I am attempting to compile the revised edition of Cinco de Mayo PCL
(put up a couple days ago on arisia.xerox.com) on top of Austin Kyoto
Common Lisp 1.122 (with the TURBO-CLOSURE patch).  If I compile with
safety 2, I get an error during the compilation of "construct.lsp":
___

(LIST))) was not evaluated successfully.

If I modify "kcl-patches.lsp" to ensure that safety is 0 throughout the
compilation, I get a segmentation violation while compiling "high.lsp".

Any suggestions?
