Sorry to bring this up again, but I am not sure if this is really a
linux kernel issue anymore, see the following code:
if(event_type == SBProcess::eBroadcastBitStateChanged) {
const StateType state = SBProcess::GetStateFromEvent(event);
switch(state) {
default:
continue;
case eStateStopped: {
static bool runOnce = false;
if(runOnce == false) {
sleep(1); // sleep a second
runOnce = true;
}
SBThread thread = process.GetThreadAtIndex(0);
SBStream stream;
As I said before that strangely it worked on the vm with kernel 4.4 so
I tried using kernel 4.4 and it still didn't work.
Next thing I did was enabling lldb's logging and what I noticed was
that when the first thread plan is being made it had wrong instruction
information that's probably because the thread was still running. So
what I tried was this runOnce with a sleep(1) and the result was as I
expected, the thread plan contained the correct instruction
information and the following breakpoints and step-overs were
correctly made.
Any chance that this issue lies deep in lldb? Would the lldb log help
to trace back the issue?
