Hi Pedro,

This error is indeed strange... I don't see a way how it could have happened
in the present code (it never occured to me).

Is the issue reproducible? Did you use a value for BITS_PER_DIMENSION in
excess of 21?

If the error is reproducible, you could try to insert the following right in
front of the call of the function "domain_topsplit_local(0, 0);" at around
line 918 in domain.c. Then, please send me the keys_XX.dat file that's
produced for the processor with the error.

    if(All.NumCurrentTiStep == 124315)
     {
       printf("BITS_PER_DIMENSION=%d\n", (int)BITS_PER_DIMENSION);
       printf("sizeof(peanokey)=%d\n", (int)sizeof(peanokey));
       FILE *fd;
       char buf[100];
       sprintf(buf, "keys_%d.dat", ThisTask);
       fd=fopen(buf, "w");
       fwrite(&NumPart, sizeof(int), 1, fd);
       fwrite(KeySorted, sizeof(peanokey), NumPart, fd);
       fclose(fd);
     }
