How are you setting igncr?  Did you read the release announcement that
you now have to use 'set -o' and not 'shopt -s' to set it?  The full

which is why igncr exists, for people unwilling to use sane line endings
in the first place.

No one else has reported that igncr is broken as implemented, so most
likely a bug in your usage and you didn't actually enable it like you
thought you had.
