I had some charts using Chartdirector and php8.3.
I upgraded my server to php8.4 , installed the appropriate lib files for ChartDirector and the result was:
1. Simple charts types like "column" and "bar" were ok.
2. More complex charts like "mscolumn" and "stackedbar" could not display and had the following php log messages:
WARNING: [pool www] child 690151 exited on signal 11 (SIGSEGV - core dumped) after 2504.710797 seconds from start
I guess something is wrong with php8.4 or my server.
I reverted back to php8.3 and all are ok.
Just to let you know
