Thomas,
There's a thread on sourceforge here http://sourceforge.net/

func=detail&aid=1825780&group_id=17203&atid=414256 I've never
encountered a seg-fault using a ppc. Further, I only encounter a
seg-fault when I install SuiteSparse *without* libcsparse.a, build
Octave-2.9.17, and try to install Octave-Forge-20071014. When I
include libcsparse.a in the SuiteSparse install, or remove
SuiteSparse entirely, I have no problem ... I've duplicated that
effort twice.
Sounds to me being an optimization problem or something like that
when building SuiteSparse?! I'm compiling SuiteSparse 3.0.0 since I
compile Octave 2.9.12 and use libcsparse.a before I compile Octave.
I also apply the patch SuiteSparse-3.0.0.diff before building
SuiteSparse without metis (don't know if you have a current SVN of
Octave-forge checked out, here is the link)

Thomas, can you tell me how to apply the patch (specific command) for
SuiteSparse?
Modify Line 77 (+F77 = f2c) of that *.diff file into your needs for
gfortran and then build another SuiteSparse,
bash~:$ export CC=gcc
bash~:$ export CFLAGS="-fno-common -no-cpp-precomp -fexceptions -
D_POSIX_C_SOURCE -D__NOEXTENSIONS__ -DNPARTITION"
bash~:$ make
try to use that created libcsparse.a instead... I don't know which
option actually fails for you but you can add one flag by another
in F77FLAGS of ./SuiteSparse/UFconfig/UFconfig.mk or in CFLAGS
above (eg. -O3 -mieee-fp ...) - doesn't Fink already have a
SuiteSparse package ready?
A SuiteSparse package was just recently added to Fink (last week).
The present problem was encountered during tests of that package.
