MEM_trigger_error_on_memory_block()

MEM_INLINE void MEM_trigger_error_on_memory_block	(	const void *	,
		const size_t	)

Util to trigger an error for the given memory block.

When ASAN is available, it will poison the memory block before accessing it, to trigger a detailed ASAN report. Otherwise, it will abort if aborting on assert is set.
