Hi,

I'll answer to myself, because I identified the problem. Although very
specific to my configuration, this may interest other people.

I use gcc-4.3.4 on AIX 5.3, which was compiled with those options:
bash-2.05a$ gcc -v
Using built-in specs.
Target: powerpc-ibm-aix5.3.0.0
Configured with: $HOME/gnusrc/gcc-4.3.4/configure --enable-threads
--enable-languages=c,c++ --prefix=$HOME/gnu --enable-threads
--disable-shared --enable-version-specific-runtime-libs --disable-nls
--with-gmp=$HOME/gnu --with-mpfr=$HOME/gnu
Thread model: aix
gcc version 4.3.4 (GCC) 

Note that this gcc version is compiled with --disable-shared (btw, gcc
4.4 branch has an issue with it on AIX, so it recommended to stick to
the 4.3 branch). Since 2009-02-14 CVS of SOSlib, Makefile.am has been
changed to revision 1.29: "changed automake/autoconf framworke to
produce both static and shared library".

Therefore if you want SOSlib to work on AIX with a gcc version with only
static libraries, you also need to compile SOSlib with static libraries,
using:

 ./configure --prefix=$PREFIX --with-libsbml=$PREFIX
--with-sundials=$PREFIX --with-libxml2=$PREFIX --disable-shared

Otherwise odeSolver segfaults at runtime.
