Building S3_0 with gcc-14 development version:
../../../src/server/sernet.c: In function 'send_ping_times_to_all':

cc1: all warnings being treated as errors
We do have an assert checking that there should never be more than MAX_NUM_CONNECTIONS rounds in the iteration, but that doesn't count as "protection" against the case the way the compiler would want.
