Dear Shunsuke Tsuchioka, dear Forum,

Thank you very much for this report (and the feedback by other users). 

I can  exactly reproduce the problem  with various versions of  GAP, 32- and
64-bit systems, with  and without packages. Therefore I hope  that it is not
too difficult to locate the bug. We will investigate the problem and let you
know when we have fixed it.

Best regards, 
    Frank Luebeck
