When I build my C++ extension on Windows (specifically PyQt with MinGW) against Python v2.6.5 it fails to run under v2.6.4. The same problem exists when building against v3.1.2 and running under v3.1.1.
The error message is...
ImportError: DLL load failed: The specified procedure could not be found.
...though I don't know what the procedure is.
When built against v2.6.4 it runs fine under all v2.6.x. When built under v3.1.1 it runs fine under all v3.1.x.
I had always assumed that an extension built with vX.Y.Z would always run under vX.Y.Z-1.
Am I wrong in that assumption, or is this a bug in the latest versions?
Thanks, Phil
