Comment (by zimmerma):
What happens is that find factors is given as input the prime factor
251...843 (I don't know why).
Of course ECM takes a long time to factor it! It seems some primality test
is missing (or wrong):
{{{
enter find_factor, n=
6695575184412459481424842051421510843842512474094970147089
1 B1= 2000
[265748496095531068869578877937, 251951573867253012259144010843]
enter find_factor, n= 251951573867253012259144010843 B1= 2399
}}}
