[gnutls-devel] GnuTLS | UB+ASAN: Fail tests if UB detected (!1136)

[Development of GNU's TLS library]

Tim Rühsen commented:


The timeout in `mini-overhead` seen in runner `UB+ASAN-Werror.Fedora.x86_64.clang` is not reproducible locally (using the Fedora 31 image from the Gitlab registry). I currently have no idea...

The failure of `ocsp-tests/ocsp-must-staple-connection` seen in runner `Debian.cross.i686-linux-gnu` seems unrelated:
```
...
=== Test 5: Server with valid certificate - expired staple ===
ERROR: ld.so: object 'datefudge.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.
Echo Server listening on IPv4 0.0.0.0 port 46538...done
Echo Server listening on IPv6 :: port 46538...done
Exiting via signal 15
Running gnutls-serv with an expired response, succeeds!
FAIL ocsp-tests/ocsp-must-staple-connection (exit status: 1)
```

Is it possible that `datefudge` doesn't work correctly and `tests/scripts/common/check_for_datefudge` does not catch it ?
