            Bug ID: 16112
           Summary: malloc_info reads uninitialized memory
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: malloc
          Assignee: unassigned at sourceware dot org
          Reporter: neleai at seznam dot cz

malloc_info could produce following entry:

 <size from="32785" to="32785" total="32785" count="1"/>
 <size from="2512305" to="2512305" total="2512305" count="1"/>
 <unsorted from="8993" to="8386112020140800621"
 total="8316306148830692230" count="7526394837682317685"/>
 </sizes>

A problem here is that we increment sizes[NFASTBINS].count but do not
initialize it to zero. Patch follows.
