Version:	5.1.41-debug	OS:	Windows (XP64, 32-bit XP SP3)
Assigned to:	Davi Arnaut	CPU Architecture:	Any

Description:
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:

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqld-debug.exe --console

      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.
