------- Comment #1 from kkojima at gcc dot gnu dot org 2009-05-12 00:43 -------
Your compilers are the gentoo special versions, aren't they?
If so, you should try the original FSF compiler sources for both
build/target compilers. See http://gcc.gnu.org/bugs.html#dontwant.
FSF 4.3/4.4 release compilers are bootstraped without problems
on sh4-unknown-linux-gnu for me.
Only I can say from the log in #1 is that your xgcc driver looks
to segfault with -dumpspecs option. Since it doesn't happen with
your gcc-4.1.2, it seems that your 4.3 compiler miscompiles something
for xgcc. If it's the case, you can bisect the problem with
replacing objects and libraries for xgcc with those compiled by
your 4.1.2 compiler.
