Dubious, test returned 9 (wstat > 2304, 0x900 > ) > Failed 3/8 subtests I see this failure maybe 1 in 20 runs (Windows 7 x64, Core i7). I suspect the problem is that winsock is invalidating the accept socket once the child socket goes out of scope, causing a race in the accept() implementation. I changes the code so the child reads a line from the socket, and the parent closes the socket. With that I had 2700 successful runs before I stopped testing. I'll try a smoke-me to see if it breaks anywhere else. Tony --- via perlbug: queue: perl5 status: new https://rt.perl.org:443/rt3/Ticket/Display.html?id=118059Thread Next
