@crackfan I've another short look at this. It seems like this is triggered by this function, which only calls a libmysqlclient function internally. This indicates that the issue is likely not in diesel itself, but in your version of libmysqlient. Please provide further information which exact version of libmysqlclient you use, otherwise there is really not much left to do here. If that information is not added I will likely close this issue next week as cannot reproduce.
