Thanks for the report. As it turns out, it's a problem related to
using the tmpfile() function. The exported function is in contrast
to other file IO functions not 64 bit aware. A fix requires to
release a new Cygwin DLL and, unfortunately, to relink your application
against the new DLL to work correctly.
As a temporary measure, create the temporary file using some other
function for now.

As a side note, the type fpos_t is 64 bit long. You should use
%lld to print it correctly.
