Hi there,
               On Wednesday I got an error trying to build the tools chain for 
hpcmips.

The hostsystem is a Linux 2.6.10 OS with gcc 3.3.4 and libc 2.3.4.  The Linux 
box is a dual xeon.

the build environment variables are set by:-

#!/bin/ksh 

#
# sandbox variables 
#
export SANDBOX=/netbsd
export XTOOLS=${SANDBOX}/tools
export PATH=${XTOOLS}/bin:$PATH
export TOOLDIR=${XTOOLS}
export DESTDIR=${SANDBOX}/dest
export MACHINE=hpcmips
export MKSHARE=yes
export MKX11=yes
export X11SRCDIR=${SANDBOX}/usr/xsrc

The error is a double free error detected in glibc and occurs when groff is 
processing grnexmpl.me and gives the following message:-

test -f grnexmpl.g || cp /netbsd/usr/src/gnu/dist/groff/doc/grnexmpl.g .

*** Error code 2

Stop.
nbmake: stopped in /netbsd/usr/src/tools/groff/obj/build/doc

I avoided this my setting MKMAN="no", cleaning out the TOOLDIR, and rerunning 
build.sh tools.

However I would like to know if this is a known problem, or is it a problem 
with my host system.

cheers
