Edit report at https://bugs.php.net/bug.php?id=79040&edit=1 ID: 79040 Updated by: requinix@php.net Reported by: ASchmidt at Anamera dot net Summary: Warning Opcode handlers are unusable due to ASLR (fall-back to file cache) Status: Open Type: Bug Package: opcache Operating System: Win x64 IIS PHP Version: 7.3.13 Block user comment: N Private report: N New Comment: Ah. What you're seeing is the result of a fix for 7.4.0 that was backported to 7.3.13: https://www.php.net/ChangeLog-7.php#7.3.13 > Fixed potential ASLR related invalid opline handler issues Previous Comments: ------------------------------------------------------------------------ [2019-12-27 21:29:19] ASchmidt at Anamera dot net I don't understand - there was NO problem with 7.3.12 and prior versions - no warning, and the OpCache GUI never complained about memory stats not existing etc.? ------------------------------------------------------------------------ [2019-12-27 21:24:45] requinix@php.net Right. What are you asking for here? To disable the warning on Windows because it'll never work anyways? Unless ASLR is disabled, but people shouldn't do that. ------------------------------------------------------------------------ [2019-12-27 20:53:17] ASchmidt at Anamera dot net >> And what if you set file_cache_only=1? << As expected, if memory caching is disabled from the onset, then there are no error messages about it being disabled dynamically due to ASLR !? ------------------------------------------------------------------------ [2019-12-27 19:54:12] requinix@php.net And what if you set file_cache_only=1? ------------------------------------------------------------------------ [2019-12-27 19:17:42] ASchmidt at Anamera dot net Description: ------------ Prior to upgrading from 7.3.12 to 7.3.13, OpCache had been functioning (incl. the previous 7.3.x versions).
