PHP Warning: Wrong COM_STMT_PREPARE response size on masquerade run.

[IanFiretoys]

hi, lately i'm finding this error on an attempted run of masquerade to anonymise a magento DB for sandboxing.

i have tried this with a few recent db dumps from the last few months, and they all fail, while i've been using it successfully for a year and a half.

results of a verbose run here:

$ php masquerade.phar run -vvv

I have double checked the config.yaml a few times, and it all seems in order. the only results i can see anywhere else all point to laravel issues, and masquerade is the only laravel user on this server as far as i'm aware. has this been seen before?

far as i can tell, foreign constraint checking is ON, and i have reset it in mysql with SET GLOBAL FOREIGN_KEY_CHECKS = 1; to no avail
