Many thanks for digging into this.  I can confirm that Emacs builds with
-fno-optimize-sibling-calls in CFLAGS.  I have a script which (now)
does:

  CFLAGS='-O3 -g0 -pipe -fno-optimize-sibling-calls' \
  ./configure ...

and it works again.

Now the question is: Is this considered a GCC bug and we should close
this report as notabug?

Best, Arash
