core dump on FreeBSD 13.2-RELEASE

I compile notify_push from this repo.
Normally it works fine but unfortunately it crashes sometimes.

In the core I found this error:

027089b0  49 6e 76 61 6c 69 64 20  73 68 61 72 65 64 20 6f  |Invalid shared o|

notify_push_core2..txt

I attached part of the core.
Any idea?

Not sure, but perhaps turning up logging will help determine if something specific is triggering it:

ok, I think I found the problem which causes the crash.
In the nginx.error-Log I found a lot Connection refused errors while notify_push was trying to to connect to localhost and localhost was an IPv6-Address [::1] which was not enabled/configured on the host.
So, it seems that after huge amount of error massages notify_push decided to crash.

After I changed the proxy_pass option in the nginx config from localhost to 127.0.0.1 every thing works well.
No error massages and no crashes anymore :-)
