Línea de trabajo

The failing assertion is revents & POLLHUP at test/core/test_pipe_pollhup.c line 58, reached through the test_pipe_pollhup method in test/test_core.py. Start by reading how WasmFS implements poll and pipe hang-up in the C++ sources, then reproduce with test\runner wasmfs.test_pipe_pollhup on Windows. Done means the test passes on Windows without changing the expected output 'done\n'.

Tried bisecting back to see if this regressed, but as far back as I could go (July 21 2026), the test still fails:

I'm pretty sure though that this test passed when I had my CI running at some point before that.
