CRASH: CppSharp.Generators.CSharp.CSharpSources.GenerateFieldGetter #"Sequence contains no matching element"

Start at CppSharp.Generators.CSharp.CSharpSources.GenerateFieldGetter, using the SidUsage.h declaration and the Setup method's module configuration as the reproduction case. Trace the field and property generation path shown in the stack trace, then verify that generating bindings for this header completes without the “Sequence contains no matching element” crash.

Brief Description

Hello I am trying to generate bindings for the Sidplay2 library (https://sourceforge.net/projects/sidplay2/files/sidplay2/sidplay-libs-2.1.1/).
I have a crash when trying to generate an header.

OS: Windows / OS X / Linux (include version and/or distro)
Windows 10 (I downloaded CppSharp 2 days ago so standing to the changelog file im here -> ## [0.11.1] - 2021-2-3)

Used headers

(inside "sidplay-libs-2.1.1\libsidutils\src\SidUsage.h"):

struct sid2_usage_t: public sid_usage_t
{
    uint_least16_t start; // Load image start address
    uint_least16_t end;   // Load image end address
    char           md5[SIDTUNE_MD5_LENGTH + 1]; // Tunes MD5 key
    uint_least16_t length;  // usage scan length

    // Copy common parts of basic usage to extended usage.
    sid2_usage_t &sid2_usage_t::operator= (const sid_usage_t &usage)
    {
        *((sid_usage_t *) this) = usage;
        return *this;
    }
};

Used settings

I only have this in my Setup method:

        public void Setup(Driver driver)
        {
            var options = driver.Options;
            options.GeneratorKind = GeneratorKind.CSharp;
            var module = options.AddModule(nameof(SIDUsage));
            module.IncludeDirs.Add(@"C:\sidplay-libs-2.1.1\libsidutils\include\sidplay\utils");
            module.Headers.Add("SidUsage.h");
            module.IncludeDirs.Add(@"C:\sidplay-libs-2.1.1\libsidplay\include\sidplay");
            module.Headers.Add("sidusage.h");
            module.IncludeDirs.Add(@"C:\sidplay-libs-2.1.1\libsidplay\include");
            module.Headers.Add("config.h");
        }

Target: MSVC/GCC/Clang

Any clue of what can cause this?

Thank you!
