AddMember causing segmentation fault #2157

Open mkandulavm opened 1 year ago

Hi

I am using latest (1.1.0) on a debian linux machine with x86_64 arch. After doing parsing of a string

rapidjson::Document document;
document.Parse(request.c_str());

calling AddMember like this

auto &allocator = document.getAllocator();
document.AddMember({"key", allocator}, {opt.language(), allocator}, allocator);

is causing segmentation fault. Here is the call stack.

rapidjson::GenericValue<rapidjson::UTF8<char>, rapidjson::MemoryPoolAllocator<rapidjson::CrtAllocator>

I believe this is something got to do with enabling some compiler flag.

Kindly help.

AddMember("member-name", obj, Document::allocator()). The 'obj' must be type of 'Value' and contain data you passed by functions SetString(), SetFloat() or etc ...
