Bug #76813 [ReO->Csd]: Access_violation_near_NULL_on_source_operand

Edit report at https://bugs.php.net/bug.php?id=76813&edit=1 ID: 76813 Updated by: cmb@php.net Reported by: songmingxuan at cert dot org dot cn Summary: Access_violation_near_NULL_on_source_operand -Status: Re-Opened +Status: Closed Type: Bug Package: Reproducible crash Operating System: ubuntu/windows PHP Version: 7.2.9 Assigned To: cmb Block user comment: N Private report: N New Comment: After further consideration, I see no point in working around missing support for default rules in very old re2c versions. After all, the segfault only occurs for erroneous input, so shouldn't be a real issue in practice anyway, what is confirmed by the age of this ticket with no further input. So, for the record, this is fixed as of PHP 8.0.0. Previous Comments: ------------------------------------------------------------------------ [2020-12-15 16:26:39] cmb@php.net The fix has been reverted from PHP-7.4 for now, because it is incompatible with re2c 0.13.5. ------------------------------------------------------------------------ [2020-12-15 16:00:18] derick@php.net Automatic comment on behalf of github@derickrethans.nl Revision: http://git.php.net/?p=php-src.git;a=commit;h=a668ce82de2987502268a10c2b867b66d24d0708 Log: Revert "Fix #76813: Access violation near NULL on source operand" ------------------------------------------------------------------------ [2020-11-30 11:34:11] cmb@php.net Automatic comment on behalf of cmbecker69@gmx.de Revision: http://git.php.net/?p=php-src.git;a=commit;h=5e15c9c41f8318a8392c2e2c78544f218736549c Log: Fix #76813: Access violation near NULL on source operand ------------------------------------------------------------------------ [2020-11-27 15:05:17] cmb@php.net The following pull request has been associated: Patch Name: Fix #76813: Access_violation_near_NULL_on_source_operand On GitHub: https://github.com/php/php-src/pull/6464 Patch: https://github.com/php/php-src/pull/6464.patch ------------------------------------------------------------------------ [2018-09-06 15:02:33] songmingxuan at cert dot org dot cn This problem.
