FreeBSD 8-Current AMD64: not compiling world, core dump with new kernel

Hello.

I've trouble compiling world on a FreeBSD 8.0-CUR/amd64 box. uname is as 
follows:

FreeBSD thusnelda.geoinf.fu-berlin.de 8.0-CURRENT FreeBSD 8.0-CURRENT #5 
r185330: Wed Nov 26 08:29:58 UTC 2008

I've cvsup'ed the most recent sources, but as the weeks before, 
compilation of 'world' stops at this point:

===> gnu/usr.bin/texinfo/doc (all)
makeinfo --no-split -I /usr/src/gnu/usr.bin/texinfo/doc -I 
/usr/src/gnu/usr.bin/texinfo/doc/../../../../contrib/texinfo/doc 
/usr/src/gnu/usr.bin/texinfo/doc/../../../../contrib/texinfo/doc/info.texi 
  -o info.info
makeinfo --no-split -I /usr/src/gnu/usr.bin/texinfo/doc -I 
/usr/src/gnu/usr.bin/texinfo/doc/../../../../contrib/texinfo/doc 
/usr/src/gnu/usr.bin/texinfo/doc/../../../../contrib/texinfo/doc/info-stnd.texi 
  -o info-stnd.info
ln -fs 
/usr/src/gnu/usr.bin/texinfo/doc/../../../../contrib/texinfo/doc/texinfo.txi 
texinfo.texi

/usr/src/gnu/usr.bin/texinfo/doc/../../../../contrib/texinfo/doc 
texinfo.texi  -o texinfo.info

gzip -cn info-stnd.info > info-stnd.info.gz
gzip -cn texinfo.info > texinfo.info.gz
1 error

Also, the kernel dated as the uname output shows is the only one that 
boots correctly on this box (DELL Poweredge 1950 with two XEON CPUs, 
dmesg follows). I can compile a kernel with the most recent sources, but 
the kernel crashes when booting (this happens also on a dual core Lenovo 
Thinkpad and affects another SMP box also, but not my private UP box). 
But this is another issue I will report separately.

Can anyone help fixing the problem above? I deleted the stuff remaining 
in /usr/obj/ and started with a freshly 'svn update', but without 
success. I guess there is something out of sync, but don't know what.

Thanks in advance,
Oliver
