Question: Segmentation fault (Zero Byte Expected) #97
Description
I got a error in console: Segmentation fault (core dumped)
A fast reproduce: https://github.com/LoongBuns/wamr-rust-sdk/tree/ohno/examples/wasm-wild
Run with this wasm https://github.com/wasm3/wasm-coremark/blob/main/coremark-minimal.wasm
I'm not quite sure what I need to enable to get iwasm to understand my needs, as this doesn't fail with other runtimes coremark .
