I took that patch and applied it to the gcc sources,
but I still see the error on ppc:
...

	linux-vdso32.so.1 =>  (0x00100000)
	libm.so.6 => /lib/power8/libm.so.6 (0x0ff00000)

Now check indeed seems to be useful: libasan should be the first libraryin the list when -fsanitize=address flag is present. Are compiler specsfor Power somehow special?

-Y
