Didier,

I was unable to reproduce this problem and it appears that
GTiffDataset::Create() does assign osFilename with pszFilename fairly
prominately in trunk and 1.6 branch.  I suspect this is a problem someone
already noticed and fixed.  I'd appreciate it if you could confirm the
behavior no longer occurs for you with trunk (or 1.6 branch if that is
convenient for you to build from).  If the problem persists, then filing
a ticket would be appropriate.

Best regards,
