Bug description:
SRU Justification:
[Impact]
* When using who, certain characters can cause issues with eglibc's vfprintf
causing memory issues and who to print 'memory exhausted'.
[Test Case]
* Download wtmp.clean.
* locale-gen en_US.UTF-8 # if necessary
* LANG=en_US.UTF-8 who wtmp.clean
* If you see 'who: memory exhausted' the test failed.
[Regression Potential]
* This patch reverts a change that fixes the issue in BZ #6530.
* The patch also adds a test case to check for handling of incomplete
multi-byte characters.
* upstream patch URL:
http://sourceware.org/git/?p=glibc.git;a=commit;h=715a900c9085907fa749589bf738b192b1a2bda5

* Description:
When running who with the attached file we get an error of "who: memory
exhausted".
$ who wtmp.clean
This works fine in newer versions of eglibc. I was able to determine that
coreutils was not the problem
by using the precise version of coreutils with the raring eglibc version. In
that case the problem went away.
In addition I've compiled the precise version for raring, and the problem is
not present.
* Versions affected:
This affects current Lucid, Oneiric, Precise and Quantal eglibc versions.
2.11.1-0ubuntu7.12
2.13-20ubuntu5.3
2.15-0ubuntu10.4
2.15-0ubuntu20.1
But does not affect Raring eglibc ( 2.17-0ubuntu1 )
