seems that the TIFFWriteScanline fails in a random access mode.
The break is asserted in line 53 of the file tif_dumpmode.c
The case is easily reproducible: just reverse the row order,
call TIFFWriteScanline from height-1 down to 0. Typically it fails after

TIFFSetField (
file,
TIFFTAG_IMAGEWIDTH,
width
);
TIFFSetField (
file,
TIFFTAG_IMAGELENGTH,
height
);
TIFFSetField (
file,
TIFFTAG_SAMPLESPERPIXEL,
4
);
TIFFSetField (
file,
TIFFTAG_BITSPERSAMPLE,
bits_per_channel // 16 in my case
);
TIFFSetField (
file,
TIFFTAG_ORIENTATION,
ORIENTATION_TOPLEFT
);
TIFFSetField (
