If it is crashing at a call to 'fwrite' then it is covered
by a
(Microsoft) knowledge base article which documents that you
must link
consistently against either multi-threaded or
single-threaded libraries.

Check the call stack at the crash point(s) - it should be
obvious if it
is crashing within a standard library function (specifically
a stdio
function.)

Since you now seem to be crashing in png_set_IHDR I think
the problem is
somewhere else - png_set_IHDR does pretty much nothing
except write to
the info structure.  Indeed the only thing I can think of is
that the
library was built with debugging on and the attempt to write
a debug
message is crashing in libc.
