The test_getaddrinfo tries to get addrinfo from "www.android.com:9999" ,at first without the hints and then with the hints. .

It fails upon first call to getaddrinfo, with trapframe printed. See "current result" for details.

make kernel
./uCore_test -s bionic -w 15 -t 45 -f src/user-ucore/testspecs/test_getaddrinfo.testspec
