I logged in into the buildbot and try to reproduce that. After 230 iterations 
of `test_eintr` I cannot reproduce the signal problem. Maybe this is an 
interaction with some other test

Pablo Galindo Salgado  added the comment:

Could it be that there is another test that is sending SIGALRM but does not 
disarm the ITIMER_REAL timer before restoring the previous handler?

TypeError: 'int' object is not callable

Can it be that thread.file has some custom deallocator/finalizer that fails?

STINNER Victor  added the comment:

Sometimes a test is killed by SIGALRM (signal 14). I don't understand how it 
can happen, since test_eintr always disarm the ITIMER_REAL timer before 
restoring the old signal handler (which kills the process when SIGARLM is 
received).

[issue35425] test_eintr fails randomly on AMD64 FreeBSD 10-STABLE Non-Debug 3.7: TypeError: 'int' object is not callable

[STINNER Victor]

New submission from STINNER Victor :

I don't understand the error, it doesn't make sense. It *seems* like 
faulthandler.cancel_dump_traceback_later attribute has been set to an int, but 
I don't see how it could be possible. Or the call raises the TypeError? But the 
call can be summarized to:

Py_CLEAR(thread.file);

and I don't see how Py_CLEAR() can trigger a TypeError.
