Sadly, this is not something I can fix. PHP is a bit weird with array assignments. Internally, the code that PHP sees is:

<pre>
compiled vars: !0 = $result
line # * op fetch ext return operands

2 0 > EXT_STMT
1 EXT_FCALL_BEGIN
2 DO_FCALL 0 'xdebug_start_code_coverage'

     3      EXT_FCALL_END

5 4 EXT_STMT
5 INIT_ARRAY 0000002:0000001 0, 'ret'
7 6 ADD_ARRAY_ELEMENT 0000002:0000001 'test', 'msg'
7 ASSIGN !0, 0000002:0000001
9 8 EXT_STMT
9 EXT_FCALL_BEGIN
10 EXT_FCALL_BEGIN
11 DO_FCALL 0 $3 'xdebug_get_code_coverage'

    12      EXT_FCALL_END                                            
    13      SEND_VAR_NO_REF                               6          $3
    14      DO_FCALL                                      1          'var_dump'
    15      EXT_FCALL_END

12 16 EXT_STMT
17 > RETURN 1
</pre>

With the array init and assignment on line 5 and 7:

<pre>
5 4 EXT_STMT
5 INIT_ARRAY 0000002:0000001 0, 'ret'
7 6 ADD_ARRAY_ELEMENT 0000002:0000001 'test', 'msg'
7 ASSIGN !0, 0000002:0000001
</pre>
