[issue37959] test_os.test_copy_file_range() killed by SIGSYS (12) on FreeBSD CURRENT buildbot

New submission from STINNER Victor <vstinner at python.org>:

https://buildbot.python.org/all/#/builders/168/builds/1356

test_nop (test.test_os.FSEncodingTests) ... ok
test_access (test.test_os.FileTests) ... ok
test_closerange (test.test_os.FileTests) ... ok

Stop.
make: stopped in /usr/home/buildbot/python/3.x.koobs-freebsd-current/build
program finished with exit code 1
elapsedTime=1562.592656

man signal says:

"12	   SIGSYS	create core image    non-existent system call invoked"

I bet that the "non-existent system call" is: copy_file_range. The configure script says:

"checking for copy_file_range... yes"


Se also bpo-37711: "regrtest: re-run failed tests in subprocesses".
