Bug #74833 [Asn]: Random crashes, seemingly related to DateTimeImmutable and mod_php

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: Thanks for that. So there might be still some leftover. Did your system generate a minidump? Or, maybe you've found some better way to repro? On your side, i would try to make some stress test while using get_defined_constants(). Like use ab with high concurrency. With or without your app, with core only and with full set of the exts you use. While the last backtrace is different, it could be still some leftover not fixed, or something completely different. Lets see for further info. Thanks.

I was not able to test it as much as I'd like because I've been fixing application bugs due to 7.2 changes. There were no crashes for the last two days. But this morning I did have a crash. Here is the error output from Visual Studio: The thread 0x28d8 has exited with code 0 (0x0). The thread 0xa50 has exited with code 0 (0x0). The thread 0x1668 has exited with code 0 (0x0).

I will upgrade to that release and continue with my testing. ------------------------------------------------------------------------ [2017-07-04 17:17:14] mike dot fellows at shaw dot ca Got it, thanks. I will let you know how the testing goes in the next few days. ------------------------------------------------------------------------ [2017-07-04 17:13:01] ab@php.net Oh, or the zip. I think I was just able to fix the permissions. Thanks. ------------------------------------------------------------------------ [2017-07-04 17:11:37] ab@php.net I've just unpacked it here http://windows.php.net/downloads/snaps/ostc/74833/pdo_sqlsrv/ts/vc15/x64/ , could you please check? Seems that's the server config that doesn't like it for some reason. Thanks. ------------------------------------------------------------------------ [2017-07-04 17:04:24] mike dot fellows at shaw dot ca @ab thanks for build the MS SQL server extension. Unfortunately I get a 401 error when I try to download it (Access is denied due to invalid credentials). Not sure how to get around that one. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
