[Mono]Assertion at /runtime/src/mono/mono/mini/mini-runtime.c:417, condition `ptr' not met

[CeSun]

I tried to run Mono on the HarmonyOS(HarmonyOS info: #110074 (comment)).

When calling the mono_jit_init function, a crash occurs and the error message is output:

After investigation, it was found that the mono_valloc function failed when calling mmap：

The value of the prot parameter here is PROT_READ | PROT_WRITE | PROT_EXEC.
HarmonyOS may not support the PROT_EXEC flag

I guessed that PROT_EXEC has something to do with jit, so I set Mono's AOT mode to MONO_AOT_MODE_INTERP_ONLY, but still crashes.

void Mono_Init()
{
    if (g_MonoDomain != nullptr)
        return;
    mono_jit_set_aot_mode(MONO_AOT_MODE_INTERP_ONLY);
    mono_trace_set_log_handler(Mono_Log, nullptr);
#ifdef __aarch64__
    mono_set_dirs("/data/storage/el1/bundle/entry/resources/resfile/BCL/arm64-v8a", "");
#elif __x86_64__
    mono_set_dirs("/data/storage/el1/bundle/entry/resources/resfile/BCL/x86_64", "");
#else 
    assert(0);
#endif
    g_MonoDomain = mono_jit_init("OpenHarmonyMonoDomain");
    assert(g_MonoDomain != nullptr);
    
    MonoAssembly* assembly = mono_domain_assembly_open(g_MonoDomain, "/data/storage/el1/bundle/entry/resources/resfile/UserLibrary/ClassLibrary1.dll");
    assert(assembly != nullptr);
    
    MonoImage* image = mono_assembly_get_image(assembly);
    assert(image != nullptr);
    
    MonoClass* main_class = mono_class_from_name(image, "ClassLibrary1", "Class1");
    assert(main_class != nullptr);

    MonoMethod* mono_method = mono_class_get_method_from_name(main_class, "Add", 2);
    assert(mono_method != nullptr);
    int a = 2;
    int b = 3;
    void *args[2] = {&a, &b};
    
    auto rtl = mono_runtime_invoke(mono_method, nullptr, args, nullptr);
    
    int res = *(int*)mono_object_unbox (rtl);
}

I would like to ask if there is a way to avoid the PROT_EXEC flag
