            Bug ID: 26110
           Summary: invalid command name in one test-case aborts entire
                    test run
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal

Say we mistakenly do:
...

and try to run the test-suite, we have:

...

So, the entire subsequent test run is aborted because of a mistake inside a
single test-case.
