This was probably the reason for:

http://gcc.gnu.org/ml/gcc-testresults/2011-07/msg02302.html

I subsequently performed the following bootstrap 
(--enable-languages=c++), which succeeded:

http://gcc.gnu.org/ml/gcc-testresults/2011-07/msg02352.html

So I changed my "lto" bootstrap script to do the following:

language=fortran
if [ $RANDOM -lt 16384 ]
then
    language=ada
fi
...
	../gcc/configure \
		...
		--enable-languages=c++,$language \

Still have to see if this will fit in the 2:20 hour gap between two 
weather forecasting runs.

Cheers,
