Segmentation fault

Describe the bug

Once I run a simple command, there is a Segmentation fault error.

To Reproduce

Run the following command:

xmap -4 8.8.8.8

Error shows: Segmentation fault.

Maybe that your machine's memory capacity is a little deficient.

Note:
XMap uses the bloomfilter to check the duplicate results, which costs some of the memory.
Choose the proper --est-elements to adapt to your memory capacity. Default to 5e8.

[idealeer]

After testing, 5e8 is fine for a 4GB memory machine.
Besides, if you do not need to de-duplicate, use --output-filter="success = 1 && (repeat = 0 || repeat = 1)" and decrease --est-elements.

[idealeer]

If the --est-elements is a little small, by default, XMap will miss some valid responses due to the de-duplicate function.

To solve this, use --output-filter="success = 1 && (repeat = 0 || repeat = 1)" .
