No redzone created before first global about address-sanitizer

yes, this is known.
We do not plan any fix (no easy one is seen)

Thanks for clarifying.

We can insert dummy globals in asan_preinit.o and build it with 
-fsanitize=address. This would only work for executables though.

I don't think there is any guarantee that globals from asan_preinit.o will 
appear at the start of .bss/.data.

I thought linker arranges file data in the order they appear on cmdline.

With -fdata-sections and linker GC it may not be as simple as that.
But I guess in most cases (if not always, with the _current_ linker 
implementation) it will be at the start of the output section. In any case, a 
dummy global won't hurt.
