1: N7CppUnit10TestCallerI10SocketTestEE.testSelect2
"writeList[0] == ss1"
in "src/SocketTest.cpp", line 441

OS:
cat /etc/redhat-release
Red Hat Enterprise Linux Client release 5.5 (Tikanga)

Kernel:
uname -a
Linux wuyli-lnx 2.6.18-194.8.1.el5 #1 SMP Wed Jun 23 10:52:51 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
SocketTest.cpp
429 char buffer[256];
430 int n = ss1.receiveBytes(buffer, sizeof(buffer));
431 assert (n == 5);
432
433 readList.clear();
434 writeList.clear();
435 exceptList.clear();
436 writeList.push_back(ss1);
437 writeList.push_back(ss2);
438 assert (Socket::select(readList, writeList, exceptList, timeout) == 2);
439 assert (readList.empty());
440 assert (writeList.size() == 2);
441 assert (writeList[0] == ss1); // fail
442 assert (writeList[1] == ss2); // fail

The test will pass if you change line 441 and 442 to the following.
441 assert (writeList[0] == ss2); // pass
442 assert (writeList[1] == ss1); // pass

Does anyone here know why? Does Poco Net implementation expect the order of writeList the same before and after select call?
