The default stack size used by libc_r is too small now that the libc DNS
resolver uses 64Kbyte buffers on the stack + other automatic variables
on either side of it. You might consider temporarily backing out the
resolver changes (although that may be a security risk) or editing
src/lib/libc_r/uthread/pthread_private.h and making PTHREAD_STACK_DEFAULT
a bit larger (1048576 should be more than enough).
