Open softlink error?

[Userzxcvbvnm]

Steps to reproduce

The test.c file is uploaded
test-c.txt
And the test.wasm file is uploaded
test-wasm.txt

using command iwasm --dir=./Data test.wasm to execute the wasm file.

We create a normal file Data/hello.txt, and a softlink file Data/link/hello_softlink.txt points to Data/hello.txt

Environment

ubuntu 20.04
Windows 10
WAMR-1.2.3

Result

In windows, WAMR could write content successfully to the source file Data/hello.txt. And this behavior could be considered as a right behavior, since Data/link/hello_softlink.txt points to Data/hello.txt

However, in Ubuntu, WAMR could not write content to Data/hello.txt. And WAMR create a new file Data/link/hello.txt and write content to Data/link/hello.txt. Maybe this is not correct.

Hi, I tried your wasm file on my Ubuntu 20.04, it seems that I didn't get the behavior like you descripted.
My Steps:

1. first have a soft link Data/link/hello_softlink.txt points to Data/hello.txt
   
2. run commands iwasm --dir=~./Data test.wasm
   

My results are:
Successfully write the content to the hello.txt and the hello_softlink.txt remained as a soft link(no matter WAMR-1.2.3 or latest commit)

Is my step the same as yours? Could you please think of anything that would influence results and make our results different?
