Bash-2.05b on darwin 7.8.0.  It seems to work in the trivial case:

  $ tar chf - README THANKS TODO | ( umask 0; tar tf - )
  README
  THANKS
  TODO

Or even:

  $ tar chf - README THANKS TODO |
  - ( umask 0; ./config/missing --run tar tf - )
  README
  THANKS
  TODO

And yet:

  $ cd libltdl
  $ sed 's,umask 0 &&,umask 0;,' Makefile > tmp && mv tmp Makefile
  $ make install
  ...
  ( cd ../../libltdl && /bin/sh
  /Users/gary/devel/savannah/libtool--devo--1.0/config/missing --run tar chf -
  COPYING.LIB README Makefile.am Makefile.in configure.ac configure ltdl.c
  ltdl.h lt_error.c libltdl/lt_error.h libltdl/lt__private.h
  libltdl/lt__strl.h libltdl/lt_system.h lt__alloc.c libltdl/lt__alloc.h

  libltdl/lt__dirent.h lt__strl.c libltdl/lt__strl.h argz_.h argz.c; ) \
  | ( umask 0; cd /Users/gary/+inst/share/libtool-2.1a/libltdl &&
  /bin/sh /Users/gary/devel/savannah/libtool--devo--1.0/config/missing
  --run tar xf -; )

Does bash behave differently when invoked as /bin/sh?

  $ grep 'SHELL[  ]*=' +build/libltdl/Makefile
  SHELL = /bin/sh
  $ (cd /bin; ls -li sh bash; )
  1716603  592 -rwxr-xr-x    1 root     wheel      603488 May 28  2004 bash
  1716586  592 -r-xr-xr-x    1 root     wheel      603488 May 28  2004 sh

Confused,
        Gary.
