At least for me it hangs already in that r216281:
timeout 20 /opt/notnfs/gcc-bisect/obj/gcc/cc1.216281 -quiet -O3
-march=pentium-m -m32 -fPIC -fno-strict-aliasing -fno-omit-frame-pointer
pr78911.c; echo $?
124
-bash-4.3$ timeout 20 /opt/notnfs/gcc-bisect/obj/gcc/cc1.216280 -quiet -O3
-march=pentium-m -m32 -fPIC -fno-strict-aliasing -fno-omit-frame-pointer
pr78911.c; echo $?
0
(the latter is instant, fraction of a second).
