Hi:

When I run `make check -j1`, all of the tests/syscalls.scm tests pass, however

when running it with `make check -j20`, the following two tests get skipped:

test-name: tcgetattr

location: /home/ds815/repos/guix/tests/syscalls.scm:553

source:

+ (test-assert

+ "tcgetattr"

+ (let ((termios (tcgetattr 0)))

+ (and (termios? termios)

+ (> (termios-input-speed termios) 0)

+ (> (termios-output-speed termios) 0))))

result: SKIP

test-name: tcsetattr

location: /home/ds815/repos/guix/tests/syscalls.scm:559

source:

+ (test-assert

+ "tcsetattr"

+ (let ((first (tcgetattr 0)))

+ (tcsetattr 0 (tcsetattr-action TCSANOW) first)

+ (equal? first (tcgetattr 0))))

result: SKIP

Running `make check -j20 TESTS="tests/syscalls.scm"` works fine and everything

passes. It seems like some other test is causing

(test-skip (if (and (file-exists? "/proc/self/fd/0")

(string-prefix? "/dev/pts/" (readlink "/proc/self/fd/0")))

2))

to skip the two tests by doing *something* to /proc/self/fd/0. Has anyone else

experienced this or is able to reproduce it?

Thanks!
