Indeed I encountered the same issues on the non-diablo JDK as well.
In the end I found a fix somewhere (can't find it off hand) but what
solved it for me was to edit src/lib/libz/Makefile and comment the
following:
.if ${MACHINE_ARCH} == "amd64"
.PATH: ${.CURDIR}/contrib/gcc_gvmat64
SRCS+= gvmat64.S
CFLAGS+= -DASMV -DNO_UNDERLINE
.endif
Then rebuild world (or just src/lib/libz if you're feeling lucky).
I've since moved the server in question onto an old 32bit box (the 64bit
one was no longer available) and didn't encounter the issue again, so I
suspect it only affects the 64bit optimised assembly version of
longest_match.
Hope this helps.
