In the current libtiff and GDAL CVS there is a bug in the new TIFFGetConfiguredCODECs function:
for (cd = registeredCODECS; cd; cd = cd->next) {
codecs = _TIFFrealloc(codecs, i * sizeof(TIFFCodec));
_TIFFmemcpy(codecs + i - 1, cd->next, sizeof(TIFFCodec));
i++;
}the "cd->next" in _TIFFmemcpy shoul be "cd" only.
This function crashs only if there is at least one registered non-builtin codec...
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.

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,
