Created attachment 896694 [details, diff] abseil-cpp: Use __builtin_ctzg and __builtin_clzg in the implementations Seems to be a GCC 14 issue. Applying the attached patch (taken from https://github.com/abseil/abseil-cpp/commit/c1e1b47d989978cde8c5a2a219df425b785a0c47) to abseil-cpp-20230802.0-r2 fixes the protobuf build error on my machine.
