It means I can't validate at all.

So you've tried to validate multiple times? I.e. does the error happen deterministically or was it more of a one off event? - David E On 17/11/18 10:05, Simon Peyton Jones via ghc-devs wrote: David I got this error on Windows today.

This isprobably not the same problem, but I also started to get an error today when running the test suite. I think the problem is with the test runner because if I directly run the test command that the test runner prints the test works as expected. Error reported during validate: Unexpected results from: TEST="T14052" ... Unexpected failures: /tmp/ghctest-_w8smutp/test spaces/perf/should_run/T14052.run T14052 [[Errno 2] No such file or directory: '/tmp/ghctest-_w8smutp/test spaces/perf/should_run/T14052.run/T14052.stats'] (ghci) If I run only this test I get a slightly different error: $ make test TEST=T14052 WAY=ghci ... Unexpected failures: perf/should_run/T14052.run T14052 [[Errno 2] No such file or directory: 'perf/should_run/T14052.run/T14052.stats'] (ghci) (note that the file path is different) However if I copy the command printed when running the test and run it the test works fine. $ HC="/home/omer/haskell/ghc/inplace/test spaces/ghc-stage2" HC_OPTS="-dcore-lint -dcmm-lint -no-user-package-db -rtsopts -fno-warn-missed-specialisations -fshow-warning-groups -fdiagnostics-color=never -fno-diagnostics-show-caret -Werror=compat -dno-debug-output " "/home/omer/haskell/ghc/inplace/test spaces/ghc-stage2" --interactive -v0 -ignore-dot-ghci -fno-ghci-history +RTS -I0.1 -RTS -fghci-leak-check -dcore-lint -dcmm-lint -no-user-package-db -rtsopts -fno-warn-missed-specialisations -fshow-warning-groups -fdiagnostics-color=never -fno-diagnostics-show-caret -Werror=compat -dno-debug-output < T14052.script > T14052.out ... $ diff T14052.out T14052.stdout (output matches the expected output) Ömer David Eichmann , 18 Kas 2018 Paz, 01:40 tarihinde şunu yazdı:

The exception is thrown by python's semaphore class. We are using it to limit the number of tests running concurrently, though I couldn't see anything obviously wrong with the relevant code. If possible, could you find out what `python --version` you have?
