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

In /ext/phar/phar_object.c:
2131                                newpath = oldpath;
but then:

2142                efree(oldpath);
2143                zend_throw_exception_ex(spl_ce_BadMethodCallException, 0 TSRMLS_CC, "phar \"%s\" exists and must be unlinked prior to conversion", newpath);
