Comment 1 Noriko Hosoi 2012-02-13 19:57:21 EST 
Steps to verify.
Run valgrind with the filter test case.
If the valgrind output files do not contain "Invalid read", the bug was verified.
Comment 5 Noriko Hosoi 2012-05-24 18:38:59 EDT 
    Technical note added. If any revisions are required, please edit the
"Technical Notes" field
    accordingly. All revisions will be proofread by the Engineering Content
Services team.

    New Contents:
Cause: Passed memory which could be modified in an API.
Consequence: Possible invalid memory access.
Fix: Duplicated memory is passed to the API.
Result: The memory check tool shows no invalid read.
