All breakpoints which are set before debug session on Android device is launched require some delay at GdbEngine startup. Otherwise they are ignored.

When I set up any breakpoint and then launch debug session, in most cases the function GdbEngine::handleResponse(const QString &buff) does not receive gdb response message "breakpoint-modified" and the breakpoint is ignored. But if the GdbEngine source code is modified in the following way:

void GdbEngine::setupInferior()
{
    CHECK_STATE(EngineSetupRequested);

    const DebuggerRunParameters &rp = runParameters();

    //runCommand("set follow-exec-mode new");
    if (rp.breakOnMain)
        runCommand({"tbreak " + mainFunction()});

    // Initial attempt to set breakpoints.
    if (rp.startMode != AttachCore) {
        showStatusMessage(tr("Setting breakpoints..."));
        showMessage(tr("Setting breakpoints..."));

///////////////////added by mine////////
        QThread::msleep(2000);

//////////////////////////////////////////////////
        attemptBreakpointSynchronization();
    }

.....................so forth with GdbEngine::setupInferior()

Then the response message "breakpoint-modified" is received, and breakpoints are successfully activated. The longer delay, the success probability is higher.

I do not understand the internal reason of the phenomenon and I suppose, that the problem should be fixed in some other way.

Grateful in advance.
