before I forget:
on amd64 the entry point to init is:

basivally, Heap::SetUp() -> node::crypto::EntropySource() -> RAND_status()
and this does the init including loading strings.

On mipsel and assuming the backtrace works:
|  #0  OPENSSL_init_crypto (opts=<optimized out>, settings=0x55645ac0) at ../crypto/init.c:563
|  #1  0x75d61f9c in std::_Rb_tree_node<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >::_M_valptr () at ../src/node.cc:1083
|  #2  0x75d62660 in std::allocator<std::__detail::_Hash_node_base*>::~allocator () at ../src/node.cc:975
|  #3  0x75d626bc in std::__get_helper<0u, node::NodeTraceStateObserver*, std::default_delete<node::NodeTraceStateObserver> > () at ../src/node.cc:1142
|  #4  0x7545b540 in __libc_start_main () from /lib/mipsel-linux-gnu/libc.so.6
|  #5  0x5557fb74 in __start ()

So it appears we get there earlier and from libstd++. It could be that the
backtrace is just nuts. Now I am a little curious why strings are not loaded
eventually…
