The build script for libFuzzer uses C++11 but it actually needs a version >= 14 because it uses user-defined literals:

llvm-project/compiler-rt/lib/fuzzer/build.sh

Line 5 in 65f40cb

$CXX -g -O2 -fno-omit-frame-pointer -std=c++11 $f -c &

llvm-project/compiler-rt/lib/fuzzer/FuzzerLoop.cpp

Line 857 in 65f40cb

/*TimeOfUnit=*/duration_cast<microseconds>(0s), {0}, DFT,

Looks like this is the same as #57980.
