Just from the type of *dp, you can see that this code
expects TIFFGetField() to be handed a double ** for
any TIFF_DOUBLE tag, even for the constant wc==1 case.
This is totally inconsistent with other fields (like
TIFF_FLOAT, above) and is also inconsistent with the
TIFFSetField() function for TIFF_DOUBLEs, which expects
to be passed a single double by value for the wc==1 case.
(See the handling of TIFFFetchNormalTag() in tif_dirread.c
for an example.) Maybe this function was written before
TIFFWriteDoubleArray() was written, not that that's an
excuse. Anyway, the new code below is a trivial modification
of the TIFF_FLOAT code above. The fact that even single
doubles get written out in the data segment and get an
offset value stored is irrelevant here - that is all
handled by TIFFWriteDoubleArray(). */
