[BUG] Incrementing stack pointer leads to auxiliary stack underflow.

[teyahb8]

Describe the bug
The attached PoC results in wasm auxiliary stack underflow error for all modes of WAMR runtime. When __heap_base value becomes less than 5264, the exception no longer occurs.

Version
iwasm 2.4.3
Commit: 4b306f0

To Reproduce
Steps to reproduce the behavior:

1. Convert the following PoC to wasm:

(module
  (global $__stack_pointer (;0;) (mut i32) i32.const 1)
  (global (;1;) i32 i32.const 5264)
  (global (;2;) i32 i32.const 1)
  (export "__heap_base" (global 1))
  (export "__data_end" (global 2))
  (export "main" (func $main))
  (func $main
    global.get $__stack_pointer
    i32.const 1
    i32.add
    global.set $__stack_pointer
    return
  )
)

2. Run the following: iwasm -f main poc.wasm

Expected behavior
Should exit with no exception based on other runtimes.

Actual Result
wasm auxiliary stack underflow
