Description

I get a pair of signal 11 errors every time nginx is closed or reloaded:
2024/08/14 16:20:41 [alert] 6935#6935: worker process 6936 exited on signal 11 (core dumped)
2024/08/14 16:20:42 [alert] 6935#6935: worker process 6937 exited on signal 11 (core dumped)
2024/08/14 16:21:06 [alert] 7352#7352: worker process 7353 exited on signal 11 (core dumped)
2024/08/14 16:21:06 [alert] 7352#7352: worker process 7354 exited on signal 11 (core dumped)

This only happens when a dynamic module is loaded, and regardless of whether it is actually called/used. code used to load it in nginx.conf:
load_module /etc/nginx/modules/ngx_http_hello_world_module.so;

In this particular test I used module code that I knew should be error free, which was the empty gif module but with all "empty_gif" replaced with "hello_world" When hello_world is called, it properly returns the empty gif.
