Works fine for me on XP 32-bit with VC9. Which compiler/build did you use?

I didn't compile myself. I downloaded VC6 x86 thread safe from windows binaries 
php download page.

Pay attention to the end of description. Windows 7 x64 doesn't have this bug, 
while Windows Server 2008 R2 do and they have much more simiral codebase than 
Windows XP and Windows Server 2008 R2.
