I've never seen a crash like this. It seems like a bug in the underlying stack, what do you think?

But I filed with more details: https://github.com/esp8266/Arduino/issues/4675

Well, never mind, it took so long for this message to be approved that it doesn't matter anymore.

It was apparently a bug in 2.3.0-rc2 that is fixed in 2.4.1 which itself was not available for download in my arduino IDE because I had http://arduino.esp8266.com/staging/pack ... index.json I was told to use a long time ago and now it seems not to be updated anymore, so it serves up an old broken version as the latest one.

and the issue is allready closed because it is no fault of the core but an issue of the (non-)portability of some libs.

Well, actually the libs were fine, I didn't change any code. I just upgraded the core to a newer version and the problem went away.
Either way, everything works now, my problem was apparently pretty much only that I was
using staging/package_esp8266com_index.json instead of stable/package_esp8266com_index.json
