Details:

I'm trying to upgrade my octave 3.2.2 with 3.3.52 (to see the progress of
fltk ploting backend, thas is muchhh faster then the gnuplot turtle),
but, after compiling with make, the command "./gnu-octave" throws a
"Segmentation Fault".

------------------------------
Software versions / settings:
------------------------------
Octave-3.3.52
Slackware 12.1 (32 bit) updated with the latest distro packages plus varios
others additions/upgrades
Gcc 4.2.3
Lapack version: 3.2.2 (compiled by myself with CFLAGS below)
Blas version: ?.?.? (http://www.netlib.org/blas/blas.tgz downloaded today)
(compiled by myself with CFLAGS below)

Compiler related enviromental variables:
* LDFLAGS=
* CXXFLAGS=-O -march=nocona
* CFLAGS=-O -march=nocona

configure command:
* ./configure --with-fltk-prefix=/usr --enable-shared --disable-docs

make command:
* make -j2

*** After the successfull compilation, if I try to run 'run-octave', I get :

address@hidden:~/oct/octave-3.3.52$ ./run-octave
Segmentation fault

*** Further try, with GDB:

address@hidden:~/oct/octave-3.3.52$ ./run-octave -g

-------------------------------------------

I think my system is pretty much well configured, because I can compile and
run sucessfully almost all .tar.gz distributed software (except those nasty
gnome dependent packages).

Lets go make octave independent of gnuplot (king of slowness) and it will be
much better.

Thanks in advance.
