E.memoryArea not working on ESP8266 (due to char-iterator ?)

Just tested with sources from github, for me it works fine.
Also tested E.memoryArea, reading a string from flash and executed with eval, works fine too.

peek32(0x3ff00054).toString(16)
="200991a"
>peek16(0x3ff00054).toString(16)
="991a"
>peek16(0x3ff00056).toString(16)
="200"
>peek8(0x3ff00054).toString(16)
="1a"
>peek8(0x3ff00055).toString(16)
="99"
>peek8(0x3ff00056).toString(16)
="0"
>peek8(0x3ff00057).toString(16)
="2"
