Exception: out of bounds memory access

[kamylee]

When i run following code in wasm.i receive an error message:Exception: out of bounds memory access

cJSON* jRoot = cJSON_CreateObject();
for (int i = 0; i < 47; i++)//Greater than 46 will prompt: out of bounds memory access
{
string strId = "id"+ std::to_string(i);
cJSON_AddStringToObject(jRoot, strId.c_str(), std::to_string(i).c_str());
}

But run this code in native is ok。
running platform:windows10

this is my setting:

setting in code:
static char global_heap_buf[21024 1024];
...
init_args.mem_alloc_option.pool.heap_buf = global_heap_buf;
init_args.mem_alloc_option.pool.heap_size = sizeof(global_heap_buf);

Increased the memory, but the problem still exists. how to solve it?

Hi, could you try increase -zstack-size and --max-memory?

[kamylee]

Yes. I hava already tried to increasing the momery for -zstack-size and --max-memory by 10 times, But the broblem has not been resolved.

I think it may be helpful to take a look at: https://github.com/bytecodealliance/wasm-micro-runtime/tree/main/samples/debug-tools You can locate which line of the source code to throw an exception
