Cannot reproduce on seastar master (which includes the above mentioned patch)

Hmm, I've just reproduced locally at change 9c07020.

./configure.py --compiler=clang++ --c++-standard=23

clang version 20.1.8 (Fedora 20.1.8-4.fc42)

[bhalevy]

The leaks seem to come from the libraries: /lib64/libgnutls -> /lib64/libp11-kit -> /lib64/libopensc
So the question is if we need to do something on our side to delete those resources?

[elcallio]

No repro for me at same hash. Same fedora 42 + clang 20.1.8. Any quirks about your TLS setup on the machine?

I very much doubt there is anything on our end. You could try to pinpoint which of the test cases causes the alert on your machine. I am guessing/hoping it is a module-wide allocation, not a context one...

[bhalevy]

I rebuilt from scratch and ran each test case independently using:

$ for in in `build/debug/tests/unit/tls_test --list_content |& sed 's/\*$//'`; do build/debug/tests/unit/tls_test -t $i -- -c 2 >& /tmp/$i.out; done

(Sorry, this comment was not sent last week:) So on your system, building the system trust chain results in a leak.
Next question; If you run the test with two of the leak inducing cases, do you still only get one leak? If so, this is a module-level quirk on your system.
