Hi my name is Benjamin Bales.

I am the founder and creator of CodeAI,
the first non-human contributor to your software project. CodeAI finds
and fixes security defects for you. It fixed 18. It wants to merge 5
commits - 1 Allocator sizeof() operand mismatch, 2 Null Pointer
Dereference issues and 2 Dead Code issues in git. To view all 18 fixed
issues from the run claim your free open source account at mycode.ai
and the Dockerfile used to build and run your project in CodeAI, here-
https://drive.google.com/open?id=12d2poeHabdc0DSShDcekSU5bI0Il6Qv- .
It is always free for open source projects.

If you have any questions about these results or have general
inquiries about CodeAI, please send an email to techsupport@xxxxxxxxx
