@tlively I added your suggestion but the lint runner is still failing, and it's failing on first line of gen-s-parser.inc ... for some reason. |

Ok, thanks for trying that. I'll just commit despite the lint failure, then. |

The stack buffer overflow is occurring because memcpy(buf, op.data(), op.size()); can write up to op.size() bytes into buf, but buf is only 33 bytes long. If op.size() is greater than 33, this will result in a buffer overflow.
