Basic Infos

With (a modified version of) the arduino-dsmr library (https://github.com/matthijskooijman/arduino-dsmr) building the included examples for ESP8266 fails with "section type conflict with __c"

Hardware

Hardware: Any ESP8266 Core Version: 2.2.0

Description

With (a modified version of) the arduino-dsmr library (https://github.com/matthijskooijman/arduino-dsmr) building the included examples for ESP8266 fails with "section type conflict with __c" when using PROGMEM string literals (e.g. INVALID_UNIT) in one of the library's headers. Should this be considered a bug in the ESP core? I can work around this, but if there's a bug in the core involved I'd prefer not to do so and wait a bit more for the bugfix.

Settings in IDE

Not appliccable
