This is fixed in both trunk and 1.4.x now. I have not tested it, though.

This is almost always a problem with the C runtime. Those are a big PITA 
to debug/understand/fix. You built this with Mingw, right ? The first 
thing to check is whether you have several C runtimes loaded: you can 
check this with the problem depends.exe: http://www.dependencywalker.com

I will try to look at this myself - I have only attempted Visual Studio 
builds on Windows 7 so far,

cheers,

David
