Unlikely. It seems to crash in NET_SockaddrEqualsInetAddress which is
native code. Though, since it's not a debug build it could be some
other close by function which is missing debug info.

Either uclibc bug, or something running out of memory. You could try to
increase the heap sizes...

Also, can you share an example that crashes like that this?
