parse with issue string when get value the program abort

[gongzhxu]

std::string strJson =
    " 8:31:09.629981 T 1660933888 media_meeting.cpp 45]"
    " Destroy MediaMeeting [0x7fce7411cc78], audio_device=(nil), video_device=(nil)";

std::string strCmd;
Json::Reader reader;
Json::Value root;
try {
	if (reader.parse(strJson.c_str(), root)) {
		strCmd = root["cmd"].asString();
	}
} catch(...) {
	return;
}

Can you work up a more minimal example? There's a lot going on in that strJson value.
What kind of abort are you seeing, specifically? Please attach repro steps and a log, I think I captured the spirit of your complaint in my repro.

Also note that Reader is deprecated, use CharReader. This isn't to say the bug is ok, but if you're writing new code and this is blocking you, consider CharReader.

Minimal repro:

The problem is that the string starting with " 8:" should fail to parse but doesn't.

Thank you for answering my question. My English is not very good，for the wrong understanding of your answer.

when the string starting with " 8:", the reader.parse should fail to parse but doesn't， then i got the assert below
test: src/lib_json/json_value.cpp:1025: Json::Value& Json::Value::resolveReference(const char*, bool): Assertion `type_ == nullValue || type_ == objectValue' failed.

you said user CharReader. i use the latest version，but compile error：

'Json::CharReaderBuilder::CharReaderBuilder()’undefined reference
‘Json::CharReaderBuilder::newCharReader() const’undefined reference
‘Json::CharReaderBuilder::~CharReaderBuilder()’undefined reference
‘Json::CharReaderBuilder::~CharReaderBuilder()’undefined reference

I will search how to use，Thank you again！
