backspace stops working in screen sessions when ncurses is compiled with -O3 Tested against a few toolchains on ppc. A simple remerge of ncurses with -O2 in the CFLAGS fixes the problem.
I wonder which optimization triggers that issue
I've added 'use ppc && replace-flags -O? -O2' to the ebuilds that exhibited the broken behaviour with -O3 in the cflags.
