To: Sascha Hauer Cc: Barebox List Hi Sascha, I can reproduce this on barebox 2016.06.0 for example with: cp /env/data/ansi-colors /env/data/ But "memcpy -s /env/data/ansi-colors -d /env/data/ansi-colors 0 0" works without problem. I try this with next barebox version (2016.07.0). Maybe it's already fixed.
