<div dir="ltr"><div class="gmail_extra"><div class="gmail_quote">On Sun, Oct 19, 2014 at 12:36 AM, René J.V. <span dir="ltr"><<a href="mailto:rjvbertin@gmail.com" target="_blank">rjvbertin@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On both my Linux and my OS X systems I've noticed that KDevelop 4.7.0 and 4.7.60 have an irregular habit of exitting after completing the parse-on-open of the projects in the session I started with. This happens regardless of whether I'm doing something in KDevelop or elsewhere.<br>
It's been suggested to set a breakpoint in KDevelop::MainWindow::~MainWindow but hasn't yet proved productive (rather the contrary; starting kdevelop under a debugger take a lot of patience on the systems I have at my disposal).<br>
<br>
So I added a qDebug output of kBackTrace() in KDevelop::MainWindow::~MainWindow, assuming I'd be able to get some idea of where the exit request came from when it happens.<br>
<br>
Turns out KDevelop exits without calling this MainWindow destructor:<br>
