Hi,

Just started using libtiff 3.8.2 on Windows (gnuwin32.sourceforge.net) and

am seeing an unhandled exception when I call the api - TIFFPrintDirectory().

I have pasted the code below. Even if I provide stdout as the 2nd parameter

to the function TIFFPrintDirectory(), i see the same crash. Please let me

know what I am missing. Further, just wanted to know how easy is it to build

a debug version of the libs for Windows?

Thanks.
