[Cyril Bouvier <Cyril.Bouvier@loria.fr>]

  Hello,

To understand where this bug comes from I will need the following log
files:

  A_8844_1553.c134.merge.merge.std*
  A_8844_1553.c134.purge.purge.std*
  A_8844_1553.c134.duplicates2.dup2.*
  A_8844_1553.c134.freerel.freerel.std*

I will also need the following files that may be bigger:

  A_8844_1553.c134.purge.purged.gz
  A_8844_1553.c134.freerel.renumber.gz
  A_8844_1553.c134.polyselect2.poly

Best regards,
Cyril Bouvier.
