<div dir="ltr">Hey Greg,<div><br></div><div>Where is the code in lldb that does the final 'resume' when we get the inferior stopped at the entry point with eLaunchFlagDebug?</div><div><br></div><div>I've got my local Linux debugging working with llgs with a band-aid fix to address the race condition, but I do consistently stop at the entry point to the program (the exec stop for the final exec into the true inferior process).</div>
<div><br></div><div>Another symptom I'm seeing (maybe it is related) is that lldb doesn't seem to know what the target is.
