ifort does so, unless the '-pad' option is given:

So does Compaq fortran, unless you specify /align:sequence :

http://h18009.www1.hp.com/fortran/docs/vf-html/pg/pgualopt.htm

xlf also does it, but marks it as an extension:

http://www-1.ibm.com/support/docview.wss?uid=swg27003923&aid=1 , page 454:

# The size of a sequence derived type is equal to the number of bytes
# of storage needed to hold all of the components of that derived type.


The point seems somewhat to be in contention as far as a standards
requirement is concerned:

I've changed the bug type to "enhancement" with this.
