Thank you Bob and Scott for your response.
I have now used uint32 for stripbytecounts and have passed argv and I am
still stuck with the following error
LAT-median-filtered.tif: Cannot read TIFF header.
Segmentation fault
and in Valgrind I get
--------------------------------------------------------------------------------------------------------------------
LAT-median-filtered.tif: Cannot read TIFF header.

==5878== If you believe this happened as a result of a stack

==5878== The main thread stack size used in this run was 8388608.
