Wrong Marshal.SizeOf on CoreRT #8274
Comments
|
EDIT: Actually, nevermind that, it seems i can't read diff's the right way around, got ported in #8222 |
|
Thank you for reporting this. #8275 has the fix. |
|
Awesome, that was swift! I'll give it a go whenever I can afford the time to build a local compiler instance. |

An updated NuGet package should be out within a day. |
|
Apart from the size, what was the effect of this bug? |
|
The layout of the marshalled view of the struct was wrong. It means both size and offsets of individual members were wrong. |
|
Confirmed working, thanks! I guess that means another MonoGame game shipping with CoreRT. |
Awesome! Are you at liberty to say which one and which platform? |
https://store.steampowered.com/app/1037020/ScourgeBringer/ It currently runs on .Net Core 3.1 but the next update will ship with CoreRT on Windows, macOS, and Linux. |

* Fix alignment of marshaled inline arrays (dotnet#8275) Fixes dotnet#8274 * Correct flags for allocating in RhpNewFastMisalign. Add fast path (dotnet#8277) * add switch case for LPUTF8Str in array element (dotnet#8278) * Wasm: Add support for DefaultConstructorOf and hence Activator.CreateInstance<T> (dotnet#8279) * Wasm: upgrade emscripten for an llvm and exception fixes. (dotnet#8281) * upgrade emscripten for some llvm and exception fixes. Correct retrieval of exception from landing pad. end c++ exception when catch found. * Update ILToWebAssemblyImporter.cs remove cut/past comment * Wasm: add support for new StackTrace().ToString() (dotnet#8201) * wasm add rethrow support (dotnet#8206) * Wasm: add support for overflow checks on signed and unsigned ints multiply (dotnet#8259) * wasm-ovf-unsigned-int * refactor for stack kind tests and add signed check * use llvm intrinsics * Wasm: bring add and sub overflow operations in line with mul (dotnet#8284) * Support for ARM64 on UNIX like systems compiler and runtime (dotnet#8271) * CoreRT-ARM64: Helper node asm code generation * CoreRT ARM64: Add additional relocation support * CoreRT ARM64: Use alternative functions for write Barriers On ARM the Jit uses a special register interface for to call the write barrier functions.

Hello there,
I stumbled upon a discrepancy between regular .Net runtimes and CoreRT when it comes to
Marshel.SizeOf().Sorry if I don't have a more precise isolated case than this, but here is a practical example from trying to get one of our project to run properly on CoreRT.
This type: https://github.com/rlabrecque/Steamworks.NET/blob/ee014372d1c1077c6fbbc2d7cb88e38fe4a56453/Plugins/Steamworks.NET/autogen/SteamCallbacks.cs#L1768
is expected to have a
Marshel.SizeOf()of 616, but CoreRT returns 612.Not very workable of an example, I concede, but I hope it helps nonetheless.
