<p>I've tried to use the latest version binary built artifacts from appveyor (also mentioned 0.94.0 link in Readme), and run on windows 7 64bit. But I've got an error about CreateFile2 not located in KERNEL32.dll. But latest 0.92.0 binary works like a charm on my OS. So I done some searches to find out what's the cause of the problem. Here are whats I found:</p>
<ol>
<li>Latest working binary: <a href="https://ci.appveyor.com/project/openstreetmap/osm2pgsql/build/0.0.352" rel="nofollow">0.0.352</a></li>
<li>First successful built binary that doesn't works: <a href="https://ci.appveyor.com/project/openstreetmap/osm2pgsql/build/0.0.397" rel="nofollow">0.0.397</a></li>
<li>The built binary that doesn't works with existing commit (previous commit was deleted so cannot compare those commits): <a href="https://ci.appveyor.com/project/openstreetmap/osm2pgsql/build/0.0.402" rel="nofollow">0.0.402</a></li>
<li>Compare of those two commits: <a href="https://github.com/openstreetmap/osm2pgsql/compare/18880484c5f4e9e7f11a51b4c2a36f601af05e5a...6c6dcd152c6c1fddfc197b94de137a44ffcf7c1f">Compare 18880484c5f4e9e7f11a51b4c2a36f601af05e5a and 6c6dcd152c6c1fddfc197b94de137a44ffcf7c1f</a></li>
</ol>
<p>Well found nothing by comparing those two (not familiar with the osm2pgsql project very well), So do some more searches and found that there is a <a href="https://github.com/madler/zlib/issues/49">regression in zlib</a> that osm2pgsql uses, with the same behavior. The regression is in zlib 1.2.8 and fixed in 1.2.9. By reading the log files of appveyor builds, found <strong>Found ZLIB: C:/libs/lib/zlib.lib (found version "1.2.8")</strong> line, so osm2pgsql uses the same version with regression. So I think the problem came from zlib. I really needs osm2pgsql latest version that works on my OS, and above results are the all things I can do to find a fix for the problem.</p>
