This problem seems to have appeared 2008-10-19. Before that date the gcc version being emerged at the end of the 1st "emerge -e system" pass was gcc-4.2.4; since 2008-10-19 the version is gcc-4.3.2. Here are some lines from the console output: if [ x"-fpic" != x ]; then \ /local/scratch/portage/sys-devel/gcc-4.3.2/work/build/./prev-gcc/xgcc -B/local/scratch/portage/sys-devel/gcc-4.3.2/work/build/./prev-gcc/ -B/local/scratch/nightly/2008-10-26/usr/i686-pc-linux-gnu/bin/ -c -DHAVE_CONFIG_H -fprofile-use -I. -I/local/scratch/portage/sys-devel/gcc-4.3.2/work/gcc-4.3.2/libiberty/../include -W -Wall -Wwrite-strings -Wc++-compat -Wstrict-prototypes -pedantic -fpic /local/scratch/portage/sys-devel/gcc-4.3.2/work/gcc-4.3.2/libiberty/hashtab.c -o pic/hashtab.o; \ else true; fi /local/scratch/portage/sys-devel/gcc-4.3.2/work/gcc-4.3.2/libiberty/hashtab.c: In function 'htab_expand': /local/scratch/portage/sys-devel/gcc-4.3.2/work/gcc-4.3.2/libiberty/hashtab.c:554: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.

I tried masking out all gcc-4.3 versions in etc/portage/package.mask. Bootstrapping then completes successfully so this can be used as a workaround.
new bootstrap snapshot has this mask
