Test Case

The test.c file is uploaded as
test-c.txt

The test.wasm file is uploaded as
test-wasm.txt

Steps to Reproduce

We create a normal file Data/hello.txt and write some initial content into the file.
using command wasmtime run --dir=./Data test.wasm to execute the wasm file.

Actual Results

In windows, wasmtime do not write any bytes into the file and prints:

Successfully get the file fd.
Current offset: 0
Wrote 0 bytes to the file.
File Size: 33 bytes
Leave snapshot.

In linux, wasmtime writes null characters (\u0000) into the file and prints:

Successfully get the file fd.
Current offset: 0
Wrote 0 bytes to the file.
File Size: 50 bytes
Leave snapshot.

There is a difference between executing the wasm file in windows and linux.
Maybe in linux, this could be a bug?

Versions and Environment

Ubuntu 20.04 (amd64)
Windows 10 (x86_64)
wasmtime 13.0.0

Thanks for the report. In the future, can you add to your reports the traces given when WASMTIME_LOG=wasmtime_wasi=trace is set in your host environment?
