I just stumbled upon on this test as it timed out for me(my test vm started swapping, so run-tests.php terminated after 60 sec). I think it would be good if we could somehow check the available ram, and skipif if it isn't enough, and I think we could also save off an str_repeat call: each str_repeat call allocates 512M of ram, so the 5th call will never happen when the bug is present, as it would allocate a little more than 2.5G ram. the test could be modified having a memory limit of 2100M and removing the sixth str_repeat call and the line '5' from the expect output.
btw: what do you think about adding a memory_get_available() function: http://stackoverflow.com/questions/2513505/how-to-get-available-memory-c-g/2513561#2513561 On Tue, Sep 13, 2011 at 8:17 PM, Christopher Jones <christopher.jo...@oracle.com> wrote: > > Dmitry, > > This is diffing for me in 5.4 (I've haven't looked at 5.3 or trunk): > > 007+ Fatal error: Allowed memory size of 3221225472 bytes exhausted at > /home/cjones/phpsrc/php/php-src/branches/PHP_5_4/ext/standard/string.c:4636 > (tried to allocate 536870913 bytes) in > /home/cjones/phpsrc/php/php-src/branches/PHP_5_4/Zend/tests/bug55509.php on > line 12 > 007- Fatal error: Allowed memory size of %d bytes exhausted (tried to > allocate %d bytes) in %s/bug55509.php on line %d > > Chris > > On 09/13/2011 12:01 AM, Dmitry Stogov wrote: >> >> dmitry Tue, 13 Sep 2011 07:01:46 +0000 >> >> Revision: http://svn.php.net/viewvc?view=revision&revision=316590 >> >> Log: >> Fixed bug #55509 (segfault on x86_64 using more than 2G memory). >> (Laruence) >> >> Bug: https://bugs.php.net/55509 (Verified) segfault on x86_64 using more >> than 2G memory >> >> Changed paths: >> U php/php-src/branches/PHP_5_3/NEWS >> A php/php-src/branches/PHP_5_3/Zend/tests/bug55509.phpt >> U php/php-src/branches/PHP_5_3/Zend/zend_alloc.c >> A php/php-src/branches/PHP_5_4/Zend/tests/bug55509.phpt >> U php/php-src/branches/PHP_5_4/Zend/zend_alloc.c >> A php/php-src/trunk/Zend/tests/bug55509.phpt >> U php/php-src/trunk/Zend/zend_alloc.c >> >> Modified: php/php-src/branches/PHP_5_3/NEWS >> =================================================================== >> --- php/php-src/branches/PHP_5_3/NEWS 2011-09-13 06:22:25 UTC (rev >> 316589) >> +++ php/php-src/branches/PHP_5_3/NEWS 2011-09-13 07:01:46 UTC (rev >> 316590) >> @@ -8,6 +8,7 @@ >> .
