But my bug report is against

-O3 -funroll-loops -ffast-math -fwhole-program -flto=jobserver
-fuse-linker-plugin

not -O3 -funroll-loops -ffast-math.  r222168 still has the same bug.

My bad - I uses

-O3 -funroll-loops -ffast-math -flto=jobserver 

linker-plugin gets used automatically for me and -fwhole-program
should be a no-op with linker-plugin.  I can re-double-check that
on Monday though.

Do you use gold or GNU ld (and which version)?  I don't use any
extra configure args for GCC and I'm using GNU ld 2.25.0 (that is,
sth from the 2.25 branch)
