Seems we've hit another problem in GCC 7, this time on Debian unstable:
Code
Compiling src/devices/bus/isa/sblaster.cpp...
g++ -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security -g0 -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -Wdate-time -D_FORTIFY_SOURCE=2 -MMD -MP -MP

../../../../../src/devices/bus/isa/sblaster.cpp: In member function 'virtual void sb_device::device_timer(emu_timer&, device_timer_id, int, void*)':

 void sb_device::device_timer(emu_timer &timer, device_timer_id tid, int param, void *ptr)
      ^~~~~~~~~

Hopefully jordi can get this escalated and fixed in a timely way. As usual, please supply preprocessed source in a bug report for the GCC people.
