Here is a (exhaustive?) list of tests which deliberately crash the interpreter:
They should reuse the new SuppressCoreFiles facility from test.support.
lambertv commentedon Sep 13, 2013
Great! Thanks for putting together a list. I've incorporated SuppressCoreFiles into these tests and have used the test suite without any errors. Again, I'm testing these on Ubuntu.

Ok, I've left a comment on the review tool above. You can click on the "review" link if you haven't received an e-mail.
lambertv commentedon Sep 14, 2013
Oops! That was careless. Fixed.
zware commentedon Sep 16, 2013
Perhaps it would be best to either combine SuppressCoreFiles and suppress_crash_popup, or provide a new construct that does so since both are used in almost every place one is used. Also, test_daemon_threads_fatal_error in test_threading should be using suppress_crash_popup, but isn't currently, which I believe falls under the scope of this issue.

Yes, these two tools must be merged into one unique portable tool. Example of names:
Doc: "On Windows, don't display the Windows Error Reporting dialog. On UNIX, disable the creation of coredump file."

test.support.SuppressCoreFiles was added by bpo-18623.
I implemented a similar tool in my tracemalloc fork:

Here's a patch that combines Valerie's patch with a merged suppress_crash_popup and SuppressCoreFiles called SuppressCrashReport.
Tests ok on Windows; I haven't been able to test on Unix yet.
pitrou commentedon Oct 7, 2013
Thanks! The patch works fine here under Linux, too (though I haven't tried to figure out if it really prevented core files from being generated).

New changeset 1cbd3d9f7d61 by Antoine Pitrou in branch 'default':
Issue bpo-18948: improve SuppressCoreFiles to include Windows crash popup suppression, and use it in more tests.

Patch committed. Thanks to both of you!
