Dear Hermann,

Which version of CADO-NFS are you using?

Can you reproduce the error if you run manually the following command?

/home/pi/cado-nfs/build/pi400-64/linalg/characters -poly
/tmp/cado.z59qan9o/c110.poly -purged /tmp/cado.z59qan9o/c110.purged.gz -index
/tmp/cado.z59qan9o/c110.index.gz -heavyblock
/tmp/cado.z59qan9o/c110.dense.bin -out /tmp/cado.z59qan9o/c110.kernel -ker
/tmp/cado.z59qan9o/c110.bwc/W -lpb0 25 -lpb1 26 -nchar 50 -t 4

And if you replace "-t 4" by "-t 1" (using only one thread)?

Best regards,
Paul Zimmermann
