Hello Christophe,
The pos file was generated with getdp version 2.0.0-cvs-20090525.
Note that it's a large simulation with 3.8e6 DoF (complex) and at nine
frequencies. The error occurs while reading the .pos file.
Here's the backtrace (note this is of version gmsh-2.3.1-cvs-20090512)

Hi Mark - Can you tell us where such large old-style lists were
generated in the code? (Are you using the old post-pro format?)
