- Tue Apr 24, 2018 1:26 pm #75583 I've never seen a crash like this. It seems like a bug in the underlying stack, what do you think?

- Thu Apr 26, 2018 7:31 pm #75622 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.

- Fri Apr 27, 2018 7:53 am #75630 and the issue is allready closed because it is no fault of the core but an issue of the (non-)portability of some libs.

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
