Getting malloc failed on test.wasm(Hello world)

[sumyrai]

Executing Test.wasm on iwasm Ubuntu 22.04 x64 returns next: ' [05:58:26:281 - 7F668EFEA740]: warning: allocate 16 bytes memory failed. Exception: allocate memory failed'

Hi, please try adding --heap-size=n for iwasm, e.g., iwasm --heap-size=32768 ...

Still get same error on ubuntu 20.04 && archlinux. Is there some way to find out why it failed?

[nerdbugg]

I attempted to use /opt/wasi-sdk/bin/clang -O3 -o test.wasm main.c to recompile test.wasm. And it run successfully.

The reason maybe the option in build.sh: -nostdlib. And wamr side do not handle it properly.
