I completely agree, but without any conditions.

The problem is that most distros nowadays disable core dumps.
So you don't get a message and you don't get a core dump.
It just falls over.  Ick.

I'm sure that with enough effort that I certainly don't have
time for, you could write a "message-and-then-abort" function
that could pull a message out of a hat (er, "ELF section"),
print it and then try to trigger and enable a core:
        struct rlimit rlim;
        getrlimit(RLIMIT_CORE, &rlim);
        rlim.rlim_cur = rlim.rlim_max;
        setrlimit(RLIMIT_CORE, &rlim);
