  "message": "fix: accept subnormal doubles when parsing (#1427) (#1695)\n\ndecodeDouble parsed numbers via `istringstream \u003e\u003e double`. For a\nsubnormal value such as `3.2114e-312`, operator\u003e\u003e sets failbit (the\nresult underflowed) even though it produced the correctly-rounded value.\nThe failure path only special-cased overflow, so subnormals were\nrejected as \"not a number\" -- meaning a value jsoncpp had just serialized\ncould fail to parse back.\n\nIn the failure path, accept the value when it is a subnormal\n(std::fpclassify(value) \u003d\u003d FP_SUBNORMAL). This keys off the value\noperator\u003e\u003e produces, which is the correctly-rounded subnormal on\nlibstdc++, libc++, and MSVC, so it needs no errno/eof heuristics. It\ndeliberately does not accept results that round to zero, so malformed\nnumbers like \"0e\" / \"0e+\" (jsonchecker fail29/fail30) and other junk are\nstill rejected. Applied to both Reader and OurReader.\n\nAdds CharReaderTest/parseSubnormal covering subnormals, a writer\nround-trip, and continued rejection of malformed numbers.",
