Apparantly there is a bug lurking somewhere in pgwin32_select(). Because if I put a #undef select right before the select in pgstat.c, the regression tests pass. I guess the bug is shown because with row level stats we simply have more data to process. And it appears only to happen on UDP sockets from what I can tell. Now, what Iwould *like* to do is to re-implement that part of the code using the Win32 APIs instead of going through select(). Since it's very isolated code. I'm going to try that and see how invasive it is, then see if it'll get accepted :-) (This would of course give us better performance in general in that codepath, since all the emulation stuff wouldn't be needed, so there's a point to doing that other than finding the obscure UDP-related bug in pgwin23_select) //Magnus
