Running radiusd -X and going through debug output I found these lines:

Changing value of PR_DUMPABLE not supported on this system
Core dumps are enabled

Which probably according to
https://github.com/FreeRADIUS/freeradius-server/blob/v3.0.x/src/lib/debug.c#L480

mean that core dumps are not really supported while running FreeRADIUS
on this OS ?
