@JonB Thanks for the explanation.

@Exotic_Devel In the link I posted is a full list of implicitly shared classes: list of classes. What I said applies to all of them and yes, QMap is one of them.

Hello Sebastian, I am seeing the same problem. The last frame on the stack after a crash points to qwebengine core qt5\qtwebengine\src\3rdparty\chromium\base\process\memory_win.cc @ 41 but its actually capturing various other exceptions from our application. Were you able to solve the problem? Thanks!

@reezeus said: Is it a good practice to use QThreadPool even if I have only one thread? I've never used QThreadPool but I can imagine that it eases scaling if you do so... The day you want to increase the number of threads, simply have a bigger pool. On the other hand if you know that one thread is what you need and will continue to need, QThread seems more reasonable IMHO.

Hi, Boot2Qt is a an enterprise feature. You should contact the Qt Company about that.
