Previous Comments: ------------------------------------------------------------------------ [2009-05-27 19:05:28] [email protected] gcc 4.3 (does not crash here when recompiling zend_execute.c with gcc 4.1) ------------------------------------------------------------------------ [2009-05-27 18:46:37] [email protected] Does not crash for me when PHP is compiled using GCC 4.1.2. What GCC version are you using? ------------------------------------------------------------------------ [2009-05-27 16:42:27] [email protected] Looks like same as http://bugs.php.net/bug.php?id=48228 (probable compiler bug). ------------------------------------------------------------------------ [2009-05-27 16:37:06] nightstorm at tlen dot pl My PHP configuration: - The script was run in the CLI environment. - No extra patches or modifications were used. - PHP was compiled **without** debugging symbols (--enable-debug seems to "fix" the problem). - It was tested on today's snapshot of PHP 5.3. ------------------------------------------------------------------------ [2009-05-27 16:30:46] nightstorm at tlen dot pl Description: ------------ The code provided below causes segfault on today's PHP 5.3 snapshot. The same script works correctly on PHP 5.2.9. I noticed that if you comment or change the line with "#1#" comment, the segmentation fault does not occur. Reproduce code: --------------- <?php class B{ public function process($x){ return $x; } } class C{ public function generate($x){ throw new Exception; } } $b = new B; $c = new C; try{ $b->process($c->generate(0)); } catch(Exception $e){ $c->generate(0);// #1# } Expected result: ---------------- The script completes its work. Actual result: -------------- Segmentation fault: Program terminated with signal 11, Segmentation fault.
