--- Comment #13 from Chen Gang <gang.chen.5i5j at gmail dot com> --- (In reply to Jeffrey A. Law from comment #12) > Please leave the bug open until a fix is committed to the trunk. OK, thanks. Could any members help to commit the related patch to the trunk? I guess, I am not the suitable member to do it: - I only reported and monitored this issue, but did not analyze it in details, this issue is fixed by another related members. - Either, at present, I have no write right for main branch (I have posted my assignment paper to FSF in 2015-01-31, I guess, it will reach FSF within 2015-02-28). Thanks.
