Description:
------------
Hi,


In /sapi/phpdbg/phpdbg_bp.c:

211                                        if ((*str)[0]) {
212                                                efree(*str);

As you can see from line 211, *str is an array.

Thanks,

Patches

There's no invalid free. The check is to prevent the literal "" (with which str is initialized) to be freed. Hence it checks whether the first byte is not 0.
