TestStdStringInField and TestArrayParams fail in debugging configuration on windows because std:string size is wrong.

Brief Description

Two tests didn't seem to succeed even after I reverted the code I was working on. The function call did go through, but some data coming from C# was uninitialized in C++. C# context everything looked fine.

It seems there is a size difference between C# std.BasicString (32 bytes) and C++ std::basic_string (40 bytes). These tests did not fail on the pull request #1887, hence I would conclude that Windows has some extra payload when compiling on debug.

How is Std.cs generated? With headers attached to Std module?
Is this just that CppSharp does not define _RELEASE or _DEBUG for clang, so the header is different from the binary?

OS: Windows

std::basic_string size on C++

std.BasicString on Std.cs on VTables.CSharp:

    namespace BasicString
    {
        [StructLayout(LayoutKind.Sequential, Size = 32, Pack = 8)]
        public unsafe partial struct __Internalc__N_std_S_basic_string__C___N_std_S_char_traits__C___N_std_S_allocator__C
        {
            internal global::Std.CompressedPair.__Internalc__N_std_S__Compressed_pair____N_std_S_allocator__C___N_std_S__String_val____N_std_S__Simple_types__C_Vb1 _Mypair;

            [SuppressUnmanagedCodeSecurity, DllImport("Std-symbols", EntryPoint = "??0?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QEAA@XZ", CallingConvention = __CallingConvention.Cdecl)]
            internal static extern __IntPtr ctorc__N_std_S_basic_string__C___N_std_S_char_traits__C___N_std_S_allocator__C(__IntPtr __instance);

            [SuppressUnmanagedCodeSecurity, DllImport("Std-symbols", EntryPoint = "??1?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QEAA@XZ", CallingConvention = __CallingConvention.Cdecl)]
            internal static extern void dtorc__N_std_S_basic_string__C___N_std_S_char_traits__C___N_std_S_allocator__C(__IntPtr __instance);
        }
    }

Doh, there was an old discussion on this #1365
