Incorrect behavior if _GLIBCXX_DEBUG is used with clang #809
Description
When the _GLIBCXX_DEBUG is used for enabling std::string support for the gdb the results from the jsoncpp changes. Elements are not found.
The following code demonstrateds this
#include <iostream>
#include <json/json.h>
int main() {
Json::CharReaderBuilder rbuilder;
std::string strJson(R"({
"array":
[
{"name":"Test1"},
{"name":"Test2"}
]
})");
Json::Value json;
auto reader(rbuilder.newCharReader());
std::string errorMessage;
if (!reader->parse(&*(strJson.begin()), &*(strJson.end()), &json, &errorMessage)) {
throw std::invalid_argument("Error during JSON-string interpretation.");
}
const Json::Value& array = json["array"];
for (const auto& o : array) {
std::cout << "name: " << o["name"].asString() << "\n";
}
std::cout << array << "\n";
}
Compiling with clang++ json.cpp -I jsoncpp/include/ -std=c++14 -ljsoncpp -L jsoncpp/src/lib_json/ -g has the output
name: Test1
name: Test2
[
{
"name" : "Test1"
},
{
"name" : "Test2"
}
]
and compiling with clang++ json.cpp -I jsoncpp/include/ -std=c++14 -ljsoncpp -L jsoncpp/src/lib_json/ -D_GLIBCXX_DEBUG -g produced
[
{
"name" : "Test1"
},
{
"name" : "Test2"
}
]
The for loop is skipped.
