+ # Test that when the address fails to parse, we do not carry on
+ # and ask lldb-server for an invalid address
+ interp.HandleCommand("memory region not_an_address", result)
+ "error: invalid address argument \"not_an_address\"")
+ # This would be found if we carried on despite the error

> Right, but this won't check that the second message is not displayed, will it? I thought we'd change this to an exact string match instead of a regex. It won't be consistent with the surrounding code, but it could be argued that the surrounding code should also be changed to use exact matches in order to ensure the error messages are really reasonable...

Right, I misunderstood. (also not sure my first version did what I thought it did either)
Changed to match the full error message, that should cover it. If you did carry on you'd get some other message that won't match, from lldb-server or otherwise.
