every new connection causes this error message to be printed;

Version: '5.1.41-enterprise-gpl-advanced-debug'  socket: ''  port: 3306  MySQL Enterprise Server - Advanced Edition Debug (GPL)
mysqld-debug: missing DBUG_RETURN or DBUG_VOID_RETURN macro in function "?func"
mysqld-debug: missing DBUG_RETURN or DBUG_VOID_RETURN macro in function "?func"

it's annoying and pollutes the error logs.

How to repeat:
mysqld-debug --console

mysql -uroot test

Suggested fix:
would be nice to change this into an assertion....
but, for now just find the function and correct the DBUG_RETURN

Verified just as described also with 5.1.41-community on 32-bit XP:

      Bug#49025: mysqld-debug: missing DBUG_RETURN or DBUG_VOID_RETURN macro in function "?func"
      The problem was that the dbug facility was being used after the
      per-thread dbug state had already been finalized. The was present
      in a few functions which invoked decrement_handler_count, which
      in turn invokes my_thread_end on Windows. In my_thread_end, the
      per-thread dbug state is finalized. Any use after the state is
      finalized ends up creating a new state.
      The solution is to process the exit of a function before the
      decrement_handler_count function is called.
     @ sql/mysqld.cc
        Process the function exit before decrement_handler_count is
        called, as it can end the per-thread dbug state on Windows.

Noted 5.1.45, 5.5.3, 6.0.14 changelogs.

For debug builds on Windows, warnings about incorrect use of
debugging directives were written to the error log. The directives
were rewritten to eliminate these messages.
