windows regression failure - prepared xacts

I am consistently seeing the regression failure shown below on my 
Windows machine. See 
http://www.pgbuildfarm.org/cgi-bin/show_log.pl?nm=loris&dt=2005-07-07%2013:54:13

(On the plus side, I am now building happily and passing regression 
tests with ASPerl, and hope to add ASPython and ASTcl to the list shortly).

cheers

andrew
