Hi Jaroslav,
To make sure I was not messing with the sources,
I have re-built everything starting from the tar balls.
The result is that the same build script (appended below)
produces a working octave 3.0.5 but a faulty octave 3.2.0.

I am not skilled enough to use dbg or valgrind
but I may try upgrading gcc and gfortran from 4.2 to 4.4 
and see if it solves the struct array problem (without
destroying my system ;-)

I will report on this later today if the upgrade goes well.

Cheers, JF



#!/bin/bash
# Build script for octave

## Pick one
version=3.1.55 ; release="" 
version=3.0.4 ; release="-rc7"
version=3.0.5 ; release=""
version=3.2.0 ; release="-rc7"

tarball=octave-$version$release.tar.gz

rm -fR cd octave-$version/
tar xzvf $tarball 
cd octave-$version
export CPPFLAGS="-I/usr/local/include/readline"
export LDFLAGS="-L/usr/local/lib"
export FFLAGS="-ff2c" ; ## for octave 3.2.0 

###  Test gcc 4.2.   Where has gcc_select gone ?
export CC=gcc-4.2
export CPP=cpp-4.2
export CXX=g++-4.2
export CXXCPP=cpp-4.2 ##      C++ preprocessor ????????

./configure 
make -j2
make check
