Diablo 6 core dumped during building of OpenJDK6

[Nerius Landys]

I have a fresh install of FreeBSD 8.1 i386 on pretty standard 5 year
old hardware (Pentium 4, Intel motherboard, 1+ gig RAM).  Installed X
without problems, then proceeded to try to install OpenJDK6 ("make
install" from /usr/ports/java/openjdk6).  Got an error, see
attachment.

Note, the system and GENERIC kernel were compiled by myself from
RELENG_8_1, my /etc/make.conf file is this:

CPUTYPE?=pentium4
CFLAGS= -O2 -fno-strict-aliasing -pipe
COPTFLAGS= -O -pipe
