iwasm with aot file fail with SIGSEGV

[peter-jerry-ye]

Subject of the issue

iwasm with an aot fails with unhandled SIGSEGV. The original wasm works fine.

Test case

WAT file: test.txt

A Moonbit version of n-body simulation

Your environment

• Host OS: Mac M1 Sonoma 14.4.1
• WAMR version, platform, cpu architecture, running mode: 7949df9, iwasm built with GC support

Steps to reproduce

wasm-tools parse test.wat -o test.wasm
wamrc --size-level=0 -o test.aot --enable-gc test.wasm # size-level=0 due to Mac M1
iwasm test.aot

Expected behavior

Print result (which I assume is 0x0:i32)

Actual behavior

unhandled SIGSEGV, si_addr: 0x67ffff79

Hi, I run it on my x86 ubuntu and didn't reproduce the error, I think it's platform specific bug. Can you try run iwasm with -v=5 to print log so that it may help locate the bug?

So if you run wasm file, will it raise the same error?

No, only the aot file fails
