commit ad3d3e8f20c95aae9d26970c169bca6f48072681
Author: Ulrich Drepper <drepper@redhat.com>
Date:   Thu Apr 8 17:12:42 2010 -0700

    Fix possibly uninitilized variable handling.
    
    If malloc errors are ignored (which say aren't by default and never
    should be) malloc in the old, slow form might use an uninitialized
    variable.
