json_value.cpp:417: Json::Value::~Value(): Assertion `false' failed

Just ran the application i got this error

i am using JsonCPP 1.5.4

[cdunn2001]

Context? Stack-trace? Line number? Any more info?

in the file json_value.cpp line number 417, release version 1.5.4
why JSON_ASSERT_UNREACHABLE is used? which is causing lot of trouble in our application.

Even though our application is crashed because of some other problem(not related to jsoncpp code), in those cases also above mentioned assertion is called, because of this we are unable to debug our application using gdb, and in the gdb always assertion trace is observed.

why assertion is used inside of destructor of Json::Value object.

Do you know what commit you are using? Maybe this problem was solved long ago. Here is the latest line 417:

 417 Value::Value(const StaticString& value) {
 418   initBasic(stringValue);
 419   value_.string_ = const_cast<char*>(value.c_str());
 420 }

I do see an assert in the destructor:

 486 Value::~Value() {
 487   switch (type_) {
 488   case nullValue:
 489   case intValue:
...
 502   default:
 503     JSON_ASSERT_UNREACHABLE;
 504   }

That should never happen, and it would be an unrecoverable error. Can you write a test to reproduce this with the latest code?

I think you can trap __assert in gdb. I don't know what else you would want to do. The code is in a bad state. The error occurred earlier, right?
