I'm not sure this is the right of the patches to follow-up around this, 
but between Jeff writing

  "Note we've got massive failures in the tester starting sometime 
  yesterday and I suspect all the threader work. So I'm going to slow 
  down on reviews of that code as we stabilize stuff."

in another thread and you 

  "There seems to be a memory consumption issue on 32 bit hosts after 
  the hybrid threader patchset.  I'm having a hard time reproducing..."

in yet another I can report that my i586-unknown-freebsd11 nightly tester 
started to fail on Sep 28 at 00:40 UTC, still failed Sep 29 and Sep 30,
and successfully passed last night.

Failures were all at the same point in all-stage2-gcc:

   cc1plus: out of memory allocating 65536 bytes after a total of 0 bytes
   gmake[3]: *** [Makefile:1136: insn-emit.o] Error 1

   cc1plus: out of memory allocating 65536 bytes after a total of 0 bytes
   gmake[3]: *** [Makefile:1136: insn-emit.o] Error 1

   cc1plus: out of memory allocating 86776 bytes after a total of 0 bytes
   gmake[3]: *** [Makefile:1136: insn-emit.o] Error 1


Is this under control now, or was last night just a lucky one?

Since that reproduced somewhat regularly, how may I be able to help?

Gerald
