It is that simply sometimes Subsurface under Windows 10 doesn't start. I
mean I click on the icon and no window and also no crash info appears. After
that I have a zombie Subsurface.exe running. I now for the first time
reproduced this with the MXE debug build and again attached drmingw to the
zombie exe.

so it appears to be entering an infinite loop when
desktop-widgets/globe.cpp calls setShowScaleBar(true);
it then tries to redirect debug output to a "NullStream" in
MarbleDebug.cpp which appears to fail on Windows.
QDebug attempts to acquire a Mutex lock but fails in
qmutex.cpp::setInternal() (wait()).
[...]
2) if the above fails try:
open the Marble source folder and find MarbleDebug.cpp and modify the
contents of the method mDebug() to be like so:
QDebug mDebug()
{
return qDebug();
}
then rebuild marble.
</pre>

Now I have this variant 2) build and running. <br>
No more occurrence of the zombie process phenomenon up to now and
also marble showing the globe plus dive site after every startup.<br>
I will continue my testing and poor <g> development work based
on this change and watch out for further recurrence of this issue or
any other.<br>
<br>
Clearly I don't know what that may mean in terms of marble: That
code piece with the "NullStream" not good for windows?!<br>
<br>
