Description:

Assertion failed: !_entered, file G:\mysql-5.1.43-winbuild\mysql-advanced-gpl-debug-5.1.43-build\include\my_dbug.h, line 29

How to repeat:
start debug build without --log-bin
run either of these:

show binary logs;
show master logs;

Verified just as described with recent 5.1.44 from bzr.

No assertion with 5.0.90-debug, so this is a regression bug.

      BUG#50780: 'show binary logs' debug assertion when binary 
      logging is disabled
      
      The server would hit an assertion because of a DBUG violation.
      There was a missing DBUG_RETURN and instead a plain return
      was used.
      
      This patch replaces the return with DBUG_RETURN.
