extract<Poco::JSON::Object::Ptr>() fails on iPhone 6

[advntss]

The code below works fine on iPhone 4s and iPhoneSimulator and Windows as well:

Poco::JSON::Parser jsonParser;
auto parsedJSON = jsonParser.parse("{\"Method\":\"multiply\",\"ArgsJson\":\"[1.1,1.1]\"}");
auto parsedResult = parsedJSON.extract<Poco::JSON::Object::Ptr>();

but fails on iPhone 5/6 with exception message

 Can not convert N4Poco9SharedPtrINS_4JSON6ObjectENS_16ReferenceCounterENS_13ReleasePolicyIS2_EEEE to 4Poco9SharedPtrINS_4JSON6ObjectENS_16ReferenceCounterENS_13ReleasePolicyIS2_EEEE

All Poco libraries for iPhone 6 was built for arm64 architecture using actual make files

./configure --config=iPhone-clang-libc++ --static --no-tests --no-samples --minimal
make POCO_TARGET_OSARCH=arm64 -s -j4

And compiler settings in XCode

Please advice how to avoid that fail or fix the sources.

UPD: debugging shows that POCO_LONG_IS_64_BIT is defned

Exception is being thrown from the code below in Var.h
Looks like pHolder->type() == typeid(T) comparison somehow returns false for the same type

    template <typename T>
    const T& extract() const
        /// Returns a const reference to the actual value.
        ///
        /// Must be instantiated with the exact type of
        /// the stored value, otherwise a BadCastException
        /// is thrown.
        /// Throws InvalidAccessException if Var is empty.
    {
        VarHolder* pHolder = content();

        if (pHolder && pHolder->type() == typeid(T))
        {
            VarHolderImpl<T>* pHolderImpl = static_cast<VarHolderImpl<T>*>(pHolder);
            return pHolderImpl->value();
        }
        else if (!pHolder)
            throw InvalidAccessException("Can not extract empty value.");
        else
            throw BadCastException(format("Can not convert %s to %s.",
                std::string(pHolder->type().name()),
                std::string(typeid(T).name())));
    }

Hi, Is there a solution to this?

I am also getting Bad cast exception.

Can not convert N4Poco9SharedPtrINS_4JSON6ObjectENS_16ReferenceCounterENS_13ReleasePolicyIS2_EEEE to N4Poco9SharedPtrINS_4JSON6ObjectENS_16ReferenceCounterENS_13ReleasePolicyIS2_EEEE.

My JSON is in the format:
{"AAA":{"BBB":"onemoresuffix.com","deleted":1}}

Code:
Poco::JSON::Parser parser;
Poco::Dynamic::Var result = parser.parse(json);
std::string value = result.convertstd::string();

Interestingly, If I run app in DEBUG mode, it works, but fails in RELEASE mode.
Is there any compiler setting that I should do?
Any help would be appreciated.

Is there anything I can do about it.
I have changed the condition to workaround
strcmp(pHolder->type().name(),typeid(T).name()) == 0 instead of pHolder->type() == typeid(T)

For arm64 builds, add the compiler flag: -fvisibility=hidden
There seems to be some sort of an issue in ParserHandler that causes Object::get to return a null when compiled without this flag.
