In order to fix the bug please replace the lines 208 and 209 in the file
'glplan7.c' (glpk 3.2.1):

      else
         that = expression();

by the following fragment:

      else
      {  AVLTREE *old_index = pdb->index;
         SPAR    *old_array = pdb->array;
         pdb->index = NULL;
         pdb->array = NULL;
         that = expression();
         pdb->index = old_index;
         pdb->array = old_array;
      }

Please note that this is a "brevi manu" patch just to fix the bug.
