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

    PASS: check_maps
    ../test-driver: line 112: 17567 Segmentation fault      (core
dumped) "$@" >> "$log_file" 2>&1
    FAIL: check_tree
    PASS: check_parsing

    PASS: check_te_checks
    ../test-driver: line 112: 17764 Segmentation fault      (core

    FAIL: check_string_list
    PASS: check_perm_macro
    ../test-driver: line 112: 17780 Segmentation fault      (core

    FAIL: check_startup
    ../test-driver: line 112: 17808 Segmentation fault      (core

    FAIL: check_ordering

with crashes like
