Error occurs when calling native function with local variable in AOT mode？ about wasm-micro-runtime HOT 8 CLOSED

Do you have a minimal reproducible example? Maybe I can give it a try to see where went wrong

from wasm-micro-runtime.

generate wasm:
/E/WorkSpace/DownLoads/wasi-sdk-21.0.m-mingw/wasi-sdk-21.0+m/bin/clang -O3 -nostdlib \ -z stack-size=32768 -Wl,--initial-memory=65536 \ -o test.wasm test.c \ -Wl,--export=main -Wl,--export=__main_argc_argv -Wl,--export=test1 \ -Wl,--export=__heap_base -Wl,--export=__data_end \ -Wl,--no-entry -Wl,--strip-all -Wl,--allow-undefined

generate aot:
wamrc -o test.aot test.wasm

code in test.c:
`void test1()
{
char *buf;

buf = malloc(1024);
if (!buf) {
    printf("malloc buf failed\n");
    return;
}

//call native function
foo2("hello 123", buf, 1024);
printf("%s\n",buf );

free(buf);

}`
it'll call native function foo2 in iwasm.exe.
enter command like this: iwasm --heap-size=16384 -f test1 test.wasm
it's run ok.
iwasm --heap-size=16384 -f test1 test.aot
it's error.

Release.zip
all test file is in Release.zip.

From you snapshot, I think maybe it's a platform specific question on windows, I tested it on ubuntu 20.04, it seems no error appears with foo2 implemented as following:

static void
foo2_wrapper(wasm_exec_env_t exec_env, char *name, char *result, int resultlen)
{
    strncpy(result, name, resultlen);
}

static NativeSymbol native_symbols[] = {
    REG_NATIVE_FUNC(foo2, "($*~)")
};

I will try it on Windows to see where went wrong

I also tried it in Ubuntu 22.04 and it ran okay with local variables. it seems to be a specific error on the Windows platform. thank you! wait for your conclusion!

Hi, could you please tell me whether you compiled the iwasm and wamrc with the latest commit? I didn't see similar error on Windows

from wasm-micro-runtime.

the commit date is 2024/3/26 17:55:53

from wasm-micro-runtime.

Can you try with the latest commit and recompile both the iwasm and wamrc to see whether the error is still?

from wasm-micro-runtime.

thank you very much,It's running ok after the update. :)
