Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:

v4:
 - return to v2 variant with using setjmp() in test. Thanks to @jacek's commit 668a4f3ff9e043cce9dd30837ccefaf528578f0c that now works in clang build.
