Edit report at https://bugs.php.net/bug.php?id=74833&edit=1 ID: 74833 Updated by: ab@php.net Reported by: mike dot fellows at shaw dot ca Summary: Random crashes, seemingly related to DateTimeImmutable and mod_php Status: Assigned Type: Bug Package: Apache2 related Operating System: Windows 7 64 bit, MacOs, Linux PHP Version: 7.0.1 to 7.1.6 Assigned To: ab Block user comment: N Private report: N New Comment: @mike thanks for the crash dump. I'll get back to you with some findings after investigating on it. Thanks. Previous Comments: ------------------------------------------------------------------------ [2017-07-17 19:12:39] mike dot fellows at shaw dot ca @ab, I have emailed you a link to the minidump with heap. ------------------------------------------------------------------------ [2017-07-17 17:54:31] ab@php.net Thanks for staying on this. Nope, bugs.php.net doesn't have this facilities. But a couple of days ago I've seen people sharing files through https://www.transfernow.net/en/ , any other service like that will suffice. The full dump were of course great. Please ensure before, that it doesn't contain any sensitive data. So basically it's get_defined_constants() that has some issues. It would still make sense to check a reproduce possibility. As it might be something simple, or something that depends on the app code or the extensions constellation, etc. Anyway, a dump is a good start already. Thanks. ------------------------------------------------------------------------ [2017-07-17 17:49:45] mike dot fellows at shaw dot ca I also have just the mini-dump. It is about 1 MByte in size. ------------------------------------------------------------------------ [2017-07-17 17:44:04] mike dot fellows at shaw dot ca I've seen another crash, this one with 7.2 alpha 3. Here is the Call Stack from Visual Studio: php7ts.dll!zif_get_defined_constants(_zend_execute_data * execute_data, _zval_struct * return_value) Line 2102 C php7ts.dll!ZEND_DO_FCALL_BY_NAME_SPEC_RETVAL_USED_HANDLER(_zend_execute_data * execute_data) Line 827 C php7ts.dll!execute_ex(_zend_execute_data * ex) Line 59085 C php7ts.dll!zend_execute(_zend_op_array * op_array, _zval_struct * return_value) Line 63117 C php7ts.dll!zend_execute_scripts(int type, _zval_struct * retval, int file_count, ...)

I have saved a mini dump with the heap. The file is about 160 MBytes. @ab if you would like the dump file does bugs.php.net have a way to upload the file somehow? ------------------------------------------------------------------------ [2017-07-12 18:04:10] mike dot fellows at shaw dot ca I've been running the 7.2 alpha3 release for almost a week now without any crashes. I only saw the one crash in alpha2 I noted in my comment above. I have not been doing any specific testing to try to trigger the bug. Just the normal development work with CakePHP, including it's Chronos package, which was triggering crashes regularly in my windows environment with 7.1. Before I changed to 7.2 alpha2/3 I was seeing about 10-15 crashes a day. So a very big improvement with the 7.2 alpha releases. I will continue to work with 7.2 and report any new crashes when/if they happen. I can also create a full dump from SQL studio if any occur. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
