Build Identifier:

Debugging a SQL query and stepping through its execution works up to the point you exit the debugger with the 'q' command. Then mclient traps with an assertion error on inactive handle

Reproducible: Always

Steps to Reproduce:

debug select count(*) from tables;
n
n
n
q

Actual Results:

Assertion `hdl->active != result' failed.
