Unless you are interested in debugging this issue (I can provide instructions, though the first thing to do is of course switch to a debug build), this will only be resolved once someone qualified happens to reproduce this in other code. ------------------------------------------------------------------------ [2020-01-09 09:28:13] bugreports at gmail dot com PHP 8.0 MASTER is still broken, i don't get why a offending change after which a predictable environment which worked before with 7.2/7.3/7.4/8.0 HEAD with and without JIT worked perfectly fine has now all sort of memory curruptions and sgefaults isn't simply reverted that long i used to build 7.2-8.0 nearly daily for weeks until that breakage ------------------------------------------------------------------------ [2019-12-31 00:02:39] bugreports at gmail dot com tried current MASTER, still random issues, differnt runs, different errors without any change and "Trying to access array offset on value of type array" is something not possible normally i guess one time even the whole test-suite passed and in the middle of the PGO-profiling spider a demo-website segfault ----------------------------------- removing that two lines from "php.ini" and everything is fine opcache.jit_buffer_size = 50000000 opcache.jit = 1235 ----------------------------------- PHP Fatal error: CPU doesn't support SSE2 in Unknown on line Trying to access array offset on value of type array profile.sh: line 267: 322863 Segmentation fault ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
