Description
Description
ext/standard/tests/file/bug69442.phpt frequently fails in CI:
https://github.com/php/php-src/actions/runs/20802473279/job/59750077725
Resulted in this output:
- read from pipe 0: string(5) "foo
- "
+ read from pipe 0: string(0) ""
read from pipe 3: string(3) "42
"
But I expected this output instead:
No error
I've observed this on macOS and PPC64.

Research direction
Start with ext/standard/tests/file/bug69442.phpt and reproduce the CI failure from the linked GitHub Actions run. Compare PTY pipe behavior on macOS and PPC64 with the expected output, then make the test reliable across supported platforms. Done means the test no longer flakes and produces the intended “No error” result.
