| Summary | 0000183: property_get on $this->undefinedvariable | ||||
| Description | property_get -n $this->somethingnonexistent crashes the debugger. In source code: retval = fetch_zval_from_symbol_table(st, keyword, keyword_end - keyword, type, current_classname, cc_length TSRMLS_CC); current_classname = fetch_classname_from_zval(retval, &cc_length TSRMLS_CC); if (retval) { st = fetch_ht_from_zval(retval TSRMLS_CC); } keyword = NULL; As retval may be nill then fetch_class_name crashes. If this issue is fixed then for some weird reason res = zend_eval_string(eval_string, ret_zval, "xdebug eval" TSRMLS_CC); crashes in _xdebug_do_eval. | ||||
| Additional Information | This issue was reported first in general list and was kind of fixed (string "$this-" crashed the property_get) | ||||
| Tags | No tags attached. | ||||
| Operating System | WIN XP | ||||
| PHP Version | 5.1.2 | ||||

The code in CVS is: if (keyword) { retval = fetch_zval_from_symbol_table(st, keyword, keyword_end - keyword, type, current_classname, cc_length T if (retval) { if (current_classname) { efree(current_classname); } current_classname = fetch_classname_from_zval(retval, &cc_length TSRMLS_CC); st = fetch_ht_from_zval(retval TSRMLS_CC); } keyword = NULL; } as you can see I only fetch the classname when retval is not NULL. So please try latest CVS, or the windows binary from http://pecl4win.php.net/ext.php/php_xdebug.dll |

|
This should be fixed in CVS by now. |
