Thanks for the hint, but it seems to be fine re/ c++ lib:

$ ldd /usr/local/bin/stellarium | fgrep ++
	libc++.so.1 => /usr/lib/libc++.so.1 (0x803e7c000)

When it crashes, it has already done a lot of config stuff and is
putting the GUI on screen; this appears as a small 300x300 pixel window
on screen, knowing already the location, but it can not resize to full
screen. I have a photo of it if someone is interested to see it
off-list.

I want to get a bt to know where to look next.
