LANG <en_US.UTF-8>

Probably my sed-4.9 is broken:

sed-4.8 is ok.
$ echo 401-creatingminlayout | sed-4.8 -e 's@[0-9]\{3,4\}-@@' -e
's@-pass[0-9]\{1\}@@'
-e s@-libstdc++@@ -e s,,, -e s@-32@@
creatingminlayout

but not sed-4.9.
$ echo 401-creatingminlayout | sed-4.9 -e 's@[0-9]\{3,4\}-@@' -e
's@-pass[0-9]\{1\}@@'
-e s@-libstdc++@@ -e s,,, -e s@-32@@
sed-4.9: -e expression #1, char 17: Invalid range end

Also my  sed-4.9 is much smaller than  sed-4.8 (both stripped).
172K  /usr/bin/sed-4.8
108K  /usr/bin/sed-4.9
