Julien,

I have submitted this in the libtiff bug database.  Luckily we have caught
this in time to fix before the TIFF 3.7.0 final release.

   http://bugzilla.remotesensing.org/show_bug.cgi?id=623

I would encourage you to add yourself to the cc list.  You might also want
to add details to help me assess the risk this cases in GDAL.

Best regards,
