(and it misses a timevar) Using -fno-fold-mem-offsets gets us to TOTAL : 92.59 11.83 104.46 1027M 92.59user 11.86system 1:44.49elapsed 99%CPU (0avgtext+0avgdata 8124868maxresident)k GCC 14.2 is TOTAL : 95.59 15.26 110.88 1028M 95.59user 15.30system 1:50.93elapsed 99%CPU (0avgtext+0avgdata 8117996maxresident)k so the culprit is identified.
