I was able to reproduce the error. It is indeed a problem of
/usr/xpg4/bin/sed. It adds an endless number of empty lines to the
output. My build normally runs with /usr/bin/sed and then it's ok.
But it should also be possible to express the sed syntax in a way
that both are happy. E.g.:
sed -e "s/yy/yyy/g" -e "/# line/d" y.tab.c > parser.c
The result is exactly the same.
