We need to remove these two lines https://github.com/bytecodealliance/wasm-micro-runtime/blob/dev/wasi_threads/samples/wasi-threads/wasm-apps/CMakeLists.txt#L32. I had to put them in this PR #1819 since there was a heap corruption problem that was making the pipeline fail. |

As discussed offline, it's ok to export free/malloc and not use app heap as long as the malloc is thread safe. |

Because stack grows from high address towards low address, the value returned by malloc is the end of the stack, not top of the stack. The top of the stack is the end of the allocated space (i.e. address returned by malloc + cluster size).
