Sometimes I got memory errors

[linwaytin]

I have a c++ function which takes a std::vector<double> as the input, and returns a double. I wrap it as follows

JLCXX_MODULE define_julia_module(jlcxx::Module& mod)
{
  mod.method("GF6", &GF6);
}

In julia, I have

module CppGF
PATH_TO_CPPLIB = "path_to_cpplib"
using CxxWrap
@wrapmodule(PATH_TO_CPPLIB)

function __init__()
    @initcxx
end
end

This does work most time, but sometimes I got memory-related errors, like free(): invalid pointer from the line

@wrapmodule(PATH_TO_CPPLIB)

Does anyone have ideas about this issue?
