Description:
------------
VLD 0.12.0 may crash when parsing break/continue statement on PHP 5.4

I found out vld_find_brk_cont() causes this problem (memory access violation).

I fixed it by this way:
srm_oparray.c, line 664, "op.op2.constant" -> "op.op2.zv->value.lval"


It works. But I do not ensure this is the right way.

Test script:
---------------
while(1) {
    break;
}

Expected result:
----------------
3   0  > > JMPZ         1, ->3
4   1  > > BRK          1, ->3
5   2*     JMP             ->0
6   3  > > RETURN       1

Actual result:
--------------
3   0  > > JMPZ         1, ->3
4   1  > > BRK          1, [[[ a random value ]]]
5   2*     JMP             ->0
6   3  > > RETURN       1


or crash directly
