[Bug 1109327] [NEW] who command gets "who: memory exhausted" for certain inputs

[Chris J Arges]

Public bug reported:

* 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 )
