I am attempting to factor a 143 digit number.

N=38665963168887228345958524071807275438375646521528126234709899468060898012114596051719213031463437427655952216764986968860908791012508565837427

> cat local.sh | sed -e '/^#/d' -e '/^$/d'
FLAGS_SIZE="-DSIZEOF_P_R_VALUES=8 -DSIZEOF_INDEX=8"

I did make cmake then rebuilt cado-nfs.

The error seems to be:
Error:Filtering - Duplicate Removal, removal pass:   terminate called
   after throwing an instance of 'std::invalid_argument'

From c145.log:
