	Sorry to react so late, I forgot to send this mail several days.

     I think the -fno-exceptions should be removed from the test 
dg-options. Otherwise your comment saying that the 'at' should throw or 
abort is wrong. I think the testsuite logic is to write neutral tests 
and challenge them with numerous different combination of options. I 
guess the testsuite is run with -fno-exceptions option before a release, 
no ?

     Moreover you are testing the mutable at method, not the const one 
involved in the patch, we should have a second test case.
