Bug #80881 [Com]: open_basedir crashes Apache

Edit report at https://bugs.php.net/bug.php?id=80881&edit=1 ID: 80881 Comment by: simbiat at outlook dot com Reported by: simbiat at outlook dot com Summary: open_basedir crashes Apache Status: Open Type: Bug Package: Safe Mode/open_basedir Operating System: Windows 10.0.19042.868] PHP Version: 8.0.3 Block user comment: N Private report: N New Comment: Nope, disabling AV did not help at all. Previous Comments: ------------------------------------------------------------------------ [2021-04-13 09:02:27] simbiat at outlook dot com Looks like something else has changed and now, when working in phpMyAdmin I am getting crashes even if basedir is not restricted. And crashes are different, now referencing php8ts.dl: https://apaste.info/yelL Not sure, but I think the only thing, that has changed on my PC since last time is... Perhaps AV update? But definitely no new KBs were installed. I will check the behavior with AV disabled, but not sure if it will provide anything. ------------------------------------------------------------------------ [2021-03-23 17:59:25] simbiat at outlook dot com It is on my machine, it's just that I use OneDrive as backup as well and it's finicky with symlinks. It's not a critical issue, that's for sure, at least, unless someone decided to host actual PROD environment on OneDrive, which seems... Unadvisable. Still, if it will be fixed someday, that would be great. ------------------------------------------------------------------------ [2021-03-23 14:05:45] cmb@php.net > Crashed on official build as well: […] It seems the memory mismanagement happens in virtual_file_ex[1], but apparently the function is inlined, so the stack backtrace isn't really helpful. > It looks like it crashes during stopping of the service. That backtrace looks like a new thread is started, and being shut down right away. This may be just a consequence of the former crash. Not sure how to go on with this, particularly since support for OneDrive hosted Websites is of very low priority for the PHP on Windows team. I suggest to either download a copy of the Website to your machine (or consider to use a VCS instead), or to disable open_basedir.

But... It looks like it crashes during stopping of the service. No logs in Apache, but here's the debug: https://apaste.info/tX0l Reports from DebugDiag for both cases - https://1drv.ms/u/s!AsaK_C2Xv0I4gunxGl8Cn2AOkewerww?e=aw1tGd ------------------------------------------------------------------------ [2021-03-18 18:22:06] cmb@php.net > I will try to replicate the same with official build tomorrow. Thank you! And thanks for the fsutil reparsePoint query outputs. These reparse tag values should be supported; let's see what the new crash dump reveals. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
