Reproduced:

$ time ./cc1plus -quiet 115639.C -fconstexpr-ops-limit=$((2**31-1))
-fconstexpr-loop-limit=$((2**31-1))

real    0m46.072s
user    0m45.541s
sys     0m0.273s

vs.

$ time ./cc1plus -quiet 115639.C -fconstexpr-ops-limit=$((2**31-1))
-fconstexpr-loop-limit=$((2**31-1))

real    0m25.545s
user    0m25.125s
sys     0m0.285s
