(gdb) print host

Checked we do have localhost entry in both /etc/hosts and /system/etc/hosts, and there is no error in dmesg/syslog. @@"

We've hooked gethostbyFoo calls, and I think maybe we should add getnameinfo hook in order to fix these netdb related errors. Then we may proceed to hunt the segmentation fault.
