My .config was very similar.  The only real difference is:

CT_THREADS="nptl"
CT_THREADS_NPTL=y

I had:

CT_THREADS="linuxthreads"
CT_THREADS_LINUXTHREADS=y

I'm trying the build now using nptl instead of linuxthreads.  So far it looks
good.  It appears something is wrong with the linuxthreads support.
