Can't reproduce. Both bbox sed (current git) and GNU sed 4.2.1
print the same thing:

{ 1,"HUP" },
{ 2,"INT" },
{ 3,"QUIT" },
{ 4,"ILL" },
{ 5,"TRAP" },
{ 6,"ABRT" },
{ 7,"BUS" },
{ 8,"FPE" },
{ 9,"KILL" },
{ 10,"USR1" },
{ 11,"SEGV" },
{ 12,"USR2" },
{ 13,"PIPE" },
{ 14,"ALRM" },
{ 15,"TERM" },
{ 16,"STKFLT" },
{ 17,"CHLD" },
{ 18,"CONT" },
{ 19,"STOP" },
{ 20,"TSTP" },
{ 21,"TTIN" },
{ 22,"TTOU" },
{ 23,"URG" },
{ 24,"XCPU" },
{ 25,"XFSZ" },
{ 26,"VTALRM" },
{ 27,"PROF" },
{ 28,"WINCH" },
{ 29,"IO" },
{ 29,"POLL" },
{ 30,"PWR" },
{ 31,"SYS" },
