Edit report at https://bugs.php.net/bug.php?id=81041&edit=1 ID: 81041 Comment by: m at m dot cz Reported by: mvorisek at mvorisek dot cz Summary: Phpstan does not finish on Windows when opcache is enabled Status: Verified Type: Bug Package: opcache Operating System: Windows PHP Version: 7.4.19 Assigned To: cmb Block user comment: N Private report: N New Comment: @cmb Did you get anywhere? Previous Comments: ------------------------------------------------------------------------ [2021-05-18 21:43:43] cmb@php.net I'm able reliably reproduce the issue (with SHM or file cache), and it is definitely a Windows only thing (on Linux, there are no problems even with file cache only[1]). Debugging this on Windows is a bit hard, due to missing helpers (like .gdbinit), but I hope to make some real progress tomorrow.

The logs started to be different (after I removed randomness from time() and simillar func calls) on line 210 362 792. Here are relevant short logs: https://github.com/mvorisek/phpstan-src/commit/f9e1b786f6a210fd8573fd8d5caf1b9cd4815e45 They differ on line 121, with opcache disabled "include" calls spl_autoload_call, with opcache disabled, "include" returns true. ------------------------------------------------------------------------ [2021-05-17 22:12:29] cmb@php.net I shall have a closer look at this. ------------------------------------------------------------------------ [2021-05-17 14:08:10] m at m dot cz About "different script result when run with opcache". Issue can be reproduced consistently on different PC, PHP version/TS. ------------------------------------------------------------------------ [2021-05-17 14:03:13] nikic@php.net To be clear, when you say "does not finish" you are talking about this fatal error, not about an infinite loop?
