[Lldb-commits] [PATCH] D62931: [lldb-server] Add setting to force 'g' packet use

Mon Nov 11 08:00:22 PST 2019

Thanks! 

lldb is trying to resume execution for some reason. I wonder if the T11 as the stop reason is causing problems, I just did it at random. I'll try changing the test to use a T02 stop reason. Baffled as to the difference in behavior, but we'll see if this matters.
