Package: afl-clang
Version: 1.95b-2
Severity: serious
Justification: makes the program unusable
File: /usr/bin/afl-clang-fast
Dear Maintainer,
The current version of afl-clang-fast in testing doesn't work at all:
$ echo "int main(){return 0;}" | afl-clang-fast -x c -

afl-llvm-pass 1.95b by <lszeke...@google.com>

clang: note: diagnostic msg: PLEASE submit a bug report to
http://bugs.debian.org/ and include the crash backtrace, preprocessed source,
and associated run script.

clang: note: diagnostic msg: Error generating preprocessed source(s) - no
preprocessable inputs.
The reason is that clang in testing is still version 3.5, while it is
already 3.6 in sid, so afl-clang got built with 3.6.
Previous versions (up to 1.94b-1+b1) used to declare this dependency like:
clang (<< 1:3.7), clang (>= 1:3.6)
However, the current version (1.95b-2) only depends on unversioned 'clang',
which is not enough.
Since debian/changelog does not mention this change, I assume that it was
not intended.
Also, please keep using a public git repository for your packaging, so
that one can more easily check which change broke something.
Best regards,
Andreas
