1. What did you do?
   If possible, provide a recipe for reproducing the error.
   Environment: I have installed mysql server using glibc binary file..
   and I execute command:

echo "update test set col1=2 where col1=1" | /usr/local/bin/soardebug -online-dsn="root:[email protected]:3307/online" -test-dsn="root:[email protected]:3307/test"

result as follows:

now I think `optimizer_181108155319_f5gh7cxdl26tcsyw\ is not correct, the correct string is "online"

4. What version of are you using (soar -version)?
