@Blzzxrd Can you run below commands individually and post results here?

lind-wasm grates/ipc-grate.cwasm file_collision_reader.cwasm
lind-wasm grates/ipc-grate.cwasm ipc_test.cwasm
lind-wasm grates/ipc-grate.cwasm pipe_stdin_reader.cwasm

[Yaxuan-w]

See README for how to compile etc.

[Blzzxrd]

Here were the results of the three commands

file_collision_reader.cwasm completed with exit code 0.

ipc_test.cwasm passed test_pipe_basic and test_pipe_eof, then hung during test_pipe_large.

pipe_stdin_reader.cwasm printed Usage: pipe_stdin_reader <expected_bytes> and exited with code 2 and returned "Usage: pipe_stdin_reader <expected_bytes>"
