This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

I'm trying to use org-mode noweb syntax to deal with erlang code that
involves bit strings.  This is an example t.org file:

#+STARTUP: indent
* top level
  #+begin_src erlang :noweb yes :tangle hello.erl
  -module(hello).
  -export(hello).
  <<defines>>
  <<functions>>
  #+end_src
** defines
:PROPERTIES:
   :noweb-ref: defines
   :END:
#+begin_src erlang :noweb no
-define(HELLO, <<"hello world">>).
#+end_src
** functions
:PROPERTIES:
   :noweb-ref: functions
   :END:
#+begin_src erlang
hello() -> ?HELLO.
#+end_src

I want it to tangle to

-module(hello).
-export(hello).
-define(HELLO, <<"hello world">>).
hello() -> ?HELLO.

Instead it tangles to

-module(hello).
-export(hello).
-define(HELLO, ).
hello() -> ?HELLO.

I also tried :no-expand yes on the begin_src line, but the result was
the same.

This is now fixed. Thank you.

Note however, that Babel properties syntax changed since this report.
Properties drawers should be, e.g.,

   :PROPERTIES:
   :header-args: :noweb-ref functions
   :END:
