I think your RAM is full.

Hi,JeanLuc As I understand the number 40000000 is the Baby’s steps and takes up 9GB of RAM. If it is reduced to 4000000, will the calculation be correct?

Using 20000000 (2^29.00) at the top of in.txt takes up 4-5gb RAM.

Yes you can reduce the babystep number to save RAM, it affects the speed (2 times less RAM, 2 times slower) but calculation should be ok. If it is not, it is a bug.

Please tell me, is this tool applicable to bitcoin? If I set such parameters, the program simply stops.

Start:2000000000000000000000000000 Stop :3FFFFFFFFFFFFFFFFFFFFFFFFFFF I fixed the issue, the program was not working when number of step per thread > 2^64. But 2^64 steps will take ages !
