Package: src:llvm-toolchain-21
Version: 1:21.1.8-10
Severity: serious
Tags: sid forky
As seen in the vbox-tools upload to migrate from LLVM 19 to 21, the
fuzzer libraries are not used anymore (or not found) when built with
LLVM 21. You can reproduce that when building with the unversioned clang:
[...]

So apparently building and shipping Debian's own libFuzzer.a is not good
enough anymore.
Two solutions here:
- stop building the libfuzzer-N-dev package
- Ship the libclang_rt.fuzzer.a (and maybe other) libraries.
This is seen with LLVM 21, 22 and 23.
