@StanFromIreland I am seeing some fuzzing errors on my branch related to this change:
https://github.com/python/cpython/actions/runs/23167480851/job/67311144393?pr=146033
For some reason I do not see the same errors on other PRs. I tried tracing where the fuzzer parses the entries, and ended up here:
https://github.com/llvm/llvm-project/blob/main/compiler-rt/lib/fuzzer/FuzzerUtil.cpp#L81
There I see no parsing of \n, but I could be wrong

Oh right, it should be "\\\\n".
