Comment 5 for bug 1040827

this has nothing todo with __nss_hosts_lookup

I had the same message with another JAVA-progrom
After installing libc6-dbg and examing the coredump, you'll see the real libc6-function

$ gdb $JAVA_HOME/bin/java core
#0 0x00007f22481e11e5 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56

So the SIGSEGV signal is coming from __memmove_ssse3

Note: i've tried openjdk-6, openjdk-7 and jdk1.7.0_21. Getting the same errror everytime.
