I do not recall seeing this test to fail.

However the test is old messy code, one thing that I guess may happen is
that there is random garbage in the siginfo_t structure we pass to the
syscall and in you case you were unlucky enough so that kernel rejects
the value, but that is just wild guess.

Btw, I've opened an issue to clean up the test in:
