What command do you use to generate the the AOT file? · wamr

I'm using WAMR-1.2.3 (the latest release as of now). When I run the sample code (wasm-micro-runtime-WAMR-1.2.3/product-mini/platforms/esp-idf), everything works fine. When I try exporting the wasm binary and run wasm2wat, I get:

(module
  (type (;0;) (func (param i32) (result i32)))
  (type (;1;) (func (param i32 i32) (result i32)))
  (type (;2;) (func (param i32)))
  (import "env" "puts" (func (;0;) (type 0)))
  (import "env" "malloc" (func (;1;) (type 0)))
  (import "env" "printf" (func (;2;) (type 1)))
  (import "env" "free" (func (;3;) (type 2)))
  (func (;4;) (type 1) (param i32 i32) (result i32)
    (local i32 i32 i32)
    global.get 0
    i32.const 32
    i32.sub
    local.tee 2
    global.set 0
    i32.const 1051
    call 0
    drop
    block  ;; label = @1
      block  ;; label = @2
        i32.const 1024
        call 1
        local.tee 3
        br_if 0 (;@2;)
        i32.const 1064
        call 0
        drop
        i32.const -1
        local.set 4
        br 1 (;@1;)
      end
      local.get 2
      local.get 3
      i32.store offset=16
      i32.const 1024
      local.get 2
      i32.const 16
      i32.add
      call 2
      drop
      i32.const 0
      local.set 4
      local.get 3
      i32.const 4
      i32.add
      i32.const 0
      i32.load16_u offset=1041 align=1
      i32.store16 align=1
      local.get 3
      i32.const 0
      i32.load offset=1037 align=1
      i32.store align=1
      local.get 2
      local.get 3
      i32.store
      i32.const 1043
      local.get 2
      call 2
      drop
      local.get 3
      call 3
    end
    local.get 2
    i32.const 32
    i32.add
    global.set 0
    local.get 4)
  (table (;0;) 1 1 funcref)
  (memory (;0;) 1)
  (global (;0;) (mut i32) (i32.const 5184))
  (global (;1;) i32 (i32.const 1082))
  (global (;2;) i32 (i32.const 5184))
  (export "memory" (memory 0))
  (export "__data_end" (global 1))
  (export "__heap_base" (global 2))
  (export "main" (func 4))
  (data (;0;) (i32.const 1024) "buf ptr: %p\0a\001234\0a\00buf: %s\00Hello world!\00malloc buf failed\00"))

I then run wamrc like this: wamrc "-o" "sample.aot" --target=riscv32 --target-abi=ilp32 sample.wasm --cpu-features=+i,+m,+c --bounds-checks=1

Then I transform the output (sample.aot) to a header file (xxd -i sample.aot >> test_wasm.h) and use that.

After the program prints "Unload WASM module", it crashes complaining that assert failed: heap_caps_free heap_caps.c:392 (heap != NULL && "free() target pointer is outside heap areas").

real freeing 0x40394780

I suspect that there's some kind of memory corruption. Can this be because I'm passing the wrong flags to wamrc, and what flags were passed to build the original source?

I tried not calling any functions (just go through the setup/tear-down procedure. It doesn't help.

Hi, the AOT file buffer should be at 4-byte aligned address, could you please try adding __aligned(4) for the array generated by xxd tool? And could you dump more log if it doesn't work? e.g., add "-v=5" for iwasm or add some os_printf in wasm_runtime_full_init?
