@srxqds I'd expect the type of exception you're getting to occur under full aot mode. Can you double check that you are indeed using the interpreter? |
yes, we use interpreter mode |
|
@steveisok @BrzVlad could you take time to fix it? |
|
What is |
the source code you can find here： https://github.com/Tornhoof/SpanJson/blob/3849bc28847e2e3ec6d2474283f512a3315b42ae/SpanJson/JsonSerializer.NonGeneric.cs#L213-L226 it can work on mono execute with jit and coreclr |
|
anyone can help to solve this problem? |
|
can you provide a full desktop console project that should fail with interpreter ? |
|
|
I'm actually not able to reproduce it on this sample with desktop interpreter. I haven't yet tried to port the code to an ios project. |
|
we are using embed mono in ue, the project is too big to share with you. anyone can help me port the c ode to ios project? |
We've tested this repro on ios device and reproduced this error, based on the iOS sample on the repo and the SpanJsonTest
The final ios sample's Makefile (where modified) The final ios sample's Program.csproj (where modified) The final ios sample's Program.cs: We first build the mono runtime on our Apple Silicon PC with |
|
We also tested this repro with release/8.0 on iOS device, the runtime did throw exception, though the message is different, but with further check, we believe this exception behavior is consistent with the release/7.0 We added the The runtime exception is like: |
|
@BrzVlad can you take time to look up this problem for .net8.0 ? |
|
we have
hi, @steveisok @BrzVlad you can reproduce by this step |
