ash bug (was: BusyBox 1.0.0-pre2 released)

Hello,

the following small script shows a bug in 1.0.0-pre2 ash. When using
set -x (for debugging) and redirection of stderr, ash somehow prints
the debug message into the wrong file. It looks like ash does the
redirection too early.

Script:
        #! /bin/sh
        exec 2> bug.log
        set -x
        echo foo > echo.log 2>&1
        set +x
        echo "bug-log:"
        cat bug.log
        echo
        echo "echo.log"
        cat echo.log

busybox ash:
        # sh bug.sh 
        bug-log:
        + set +x
        
        echo.log
        + echo foo
        foo
        
bash:
        /home/jw5> sh bug.sh 
        bug-log:
        + echo foo
        + set +x
        
        echo.log
        foo
        
regards,
Jean
