Package: clang-14
Version: 1:14.0.0-1
Severity: grave
Using address sanitizer with Clang 14 produces broken binaries while
using Clang 13 works fine, e.g for SELint:
git clone https://github.com/TresysTechnology/selint
cd selint/
./autogen.sh
./configure CC=clang-14 CFLAGS='-O1 -g -fsanitize=address
-fsanitize-address-use-after-scope -fno-omit-frame-pointer'
make check
results in
