I am getting really strange results using libpng dll functions. Values
retrieved from function calls by return, seems to be random garbage. But
retrieving values by pointer (function arguments) works ok.
tested setups:
1. libpng13.dll/libpng13.lib v1.2.16
built on my machine with visualstudio2005. lib converted with
coffimplib.exe.
2.libpng13.dll/libpng13.lib v1.2.8
Precompiled. From gnuwin32.sourceforge.net. lib converted with
coffimplib.exe.
Here is minimal test case:
pngtest.d - http://paste.dprogramming.com/dpf5eoyg.php
libpng/api.d - http://paste.dprogramming.com/dpi42vqv.php
Tested with dmd v1.006, and v0.175 (for sake of experiment).
Any help would be really appreciated, I'm about to pull my hairs out =(
