The use of '__memx' - how can i resolve code issue?
The changelog you quote mentions __memx only w.r.t. static initialisers, not named address spaces in general.   In reality, named address spaces like __memx were added to GCC...

ATTiny85 and the Reset pin
Another option would be to simply put the button on /RESET as a proper reset button.  Then in your code, monitor the sensitivity pot for changes for, say, only the first...

Wake up behavior upon interrupt vs. reset vs. board power cycle
Pressing the reset button will trigger an external reset.   Power cycling the board will trigger a power-on reset.   A reset is a reset, regardless of the source. ...
