[1.x] Segmentation Fault in janus_log_getbuf() at log.c

[Ajitshiva]

What version of Janus is this happening on?
Latest

Have you tested a more recent version of Janus too?
Yes

Was this working before?
This is the first time I am facing this crash for the past 2 years.

Is there a gdb or libasan trace of the issue?

Additional context

static janus_log_buffer *janus_log_getbuf(void) {
        /*** some code  ***/
	if (b == NULL) {
		b = g_malloc(INITIAL_BUFSZ + sizeof(*b));
		// we are suspecting before b->allocated set to INITIAL_BUFSZ, b set to NULL by other thread.
		b->allocated = INITIAL_BUFSZ;
		b->next = NULL;
	}
	return b;
}

The process was aborted due to a malloc failure.

1. Are you running a customized version of the server?
2. Can you provide some details about the environment (Linux distro, standard lib etc.) ?
3. Run Janus with sanitizers enabled

[Ajitshiva]

1. Yes we have done very very minimal customization. But those changes should not affect the log.c malloc part.
2. Environment is AWS instance (Debian 12 bookworm OS)
3. I will try to Run Janus with sanitizers enabled

@Ajitshiva we actually decided to change the way logging is performed, since it was long overdue. Please test the new PR instead.

@Ajitshiva any feedback?
