New submission from Michelle Johnson <[email protected]>:
CentOS 7.6, running Linux gl-build.arc-ts.umich.edu 3.10.0-957.10.1.el7.x86_64
#1 SMP Mon Mar 18 15:06:45 UTC 2019 x86_64 on Intel(R) Xeon(R) Gold 6140 CPU @
2.30GHz.
Using gcc 8.2.0 compiled from source to build python 3.7.4 from source, make
test fails with the following errors:
```
0:00:22 load avg: 3.12 [402/416/1] test_faulthandler failed
test test_faulthandler failed -- Traceback (most recent call last):
File "/tmp/shellysw/build/Python-3.7.4/Lib/test/test_faulthandler.py", line
724, in test_register_chain
self.check_register(chain=True)
File "/tmp/shellysw/build/Python-3.7.4/Lib/test/test_faulthandler.py", line
702, in check_register
self.assertEqual(exitcode, 0)
AssertionError: -11 != 0
```
I found a similar error reported in RedHat bugzilla (1687171) and tried running
the script provided by Victor Stinner, and this closed issue on GitHub seems
like it might be related?
#32 because of the Skylake chipset.
Script:
```
import faulthandler, signal, os
def handler(signum, frame):
handler.called = True
handler.called = False
faulthandler.enable()
signum = signal.SIGUSR1
signal.signal(signum, handler)
faulthandler.register(signum, chain=True)
os.kill(os.getpid(), signum)
print("called", handler.called)
```
It produced a segmentation fault. I also ran that script using the python 3.6.6
binary that came installed with centos and it also produced a segmentation
fault as well.
