Emilio's recent-ish change (commit f3ced3c5928) maybe?
Nigel -- what host architecture are you building for?

Thanks for running with this. I'm starting to suspect that my set-up is
broken and I'm trying to mix and match gcc-6 and 7.
My CFLAGS are:
-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -O2 -W -Wformat=2 -Wswitch
-Wshadow -Wwrite-strings -Wuninitialized -Wall -pipe
-fomit-frame-pointer -D_FORTIFY_SOURCE=2 -Wpointer-arith
-Wstrict-prototypes -fstack-protector -Wstack-protector -Wextra
-Wbad-function-cast -Wcast-align -Wcast-qual -Wdisabled-optimization
-Wendif-labels -Wfloat-equal -Wformat-nonliteral -Winline
-Wmissing-declarations -Wmissing-prototypes -Wnested-externs
-Wpointer-arith -Wundef -Wformat-security -ftree-vectorize -msse
-mfpmath=sse -msse2 -mssse3 -msse4.1 -msse4.2 -fdiagnostics-color=auto
-mtune=native -march=native
My configure options are:
# QEMU configure log Fri 7 Jul 11:31:59 EDT 2017
# Configured with: './configure' '--enable-linux-aio' '--enable-kvm'
'--enable-curses'
I'm going to explicitly add '-cc=gcc-7' and see if that helps.
