A GCC trunk bootstrap fails with:

gcc   -g -fkeep-inline-functions -DIN_GCC   -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Wold-style-definition -Wc++-compat -fno-common  -DHAVE_CONFIG_H -DGENERATOR_FILE  -o build/gengtype \

                    -S ../../trunk/gcc -I gtyp-input.list -w gtype.state
build/gengtype  \
                    -r gtype.state

real	8m9.482s
user	4m0.680s
sys	1m37.547s

Looking at top at the time of failure:

Mem:    681844k total,   368152k used,   313692k free,     6076k buffers
Swap:        0k total,        0k used,        0k free,   240456k cached

/home is mounted over NFS, swap is commented out, make bootstrap after a
clean boot, /etc/rc.local has:

sysctl -w vm.overcommit_memory=2
echo 0 > /proc/sys/kernel/randomize_va_space

In a different situation, with mem=768M in a previous test I got various issues reported in /var/log/messages

rsalveti asked me to open a report.
