YAML::LoadFile get bad allcation exception on windows

[jsrdzhk]

I build shared library with cmake by:

cmake -B build_v140_x64 -G "Visual Studio 14 2015" -A x64 -DYAML_BUILD_SHARED_LIBS=on -DYAML_CPP_BUILD_TESTS=off
cmake --build build_v140_x64 --config Release

The demo yaml file is:

diagnoser:
  trade-gw:
    enable: false
test1: 10

I link the yaml-cpp.dll by:

find_library(
        YAML_CPP_LIB
        NAMES yaml-cpp.lib
        PATHS ${THIRD_PARTY_LIB_PATH} NO_DEFAULT_PATH)
target_link_libraries(test_yaml_cpp PRIVATE ${YAML_CPP_LIB})

test code:

int main() {
    try {
        fs::path yamlPath = "C:\\my_proj\\cpp_test\\src\\test_yaml_cpp\\checker.yaml";
        if (!fs::exists(yamlPath)) {
            return -1;
        }
        YAML::Node root = YAML::LoadFile(yamlPath.string());
        std::cout << "root size:" << root.size() << std::endl;
        auto diag_node = root["diagnoser"];
        if (diag_node) {
            std::cout << diag_node["trade-gw"]["enable"].as<bool>() << std::endl;
        }
        std::cout << root["test1"].as<int>() << std::endl;
    } catch (const YAML::ParserException& e) {
        std::cout << "ParserException parse config file failed:" << e.msg << std::endl;
        return -1;
    } catch (const YAML::BadFile& e) {
        std::cout << "BadFile parse config file failed:" << e.msg << std::endl;
        return -2;
    } catch (const std::exception& e) {
        std::cout << "parse config file failed:" << e.what() << std::endl;
        return -3;
    }
    return 0;
}

output:

parse config file failed:bad allocation

What version of yaml-cpp?

yaml-cpp-0.7.0

[jbeder]

Also this is super surprising and you might do better by asking on Stack Overflow.

but these code works well on linux

[jbeder]

Right, but the problem might be in your windows setup and not in yaml-cpp.

Also, try at HEAD instead of 0.7.0 and see if that helps.
