guile-1.8.5 segfaults while building on ppc with gcc-4.3 and -O2

Hi,

I've had some reports that guile-1.8.5 segfaults while building on ppc with
gcc-4.3 and -O2[1]. It seems to build fine with -O1 instead. Did anyone else see
this behavior?

Yes, sounds similar to what we saw on ppc with the Debian build.
Please try these patches:
http://git.savannah.gnu.org/gitweb/?p=guile.git;a=commit;h=9143131b2766d1e29e05d61b5021395b4c93a6bc

(You may also want to check the actual Debian diffs, in case there's
something else I've forgotten.)
