Hi Dimitri, I just tried it here. The same problem is happening with kernel 6.7 and the same workaround (disabling ASLR) works.

Example of failure:


clang++-$VERSION -O1 -g -fsanitize=address -fno-omit-frame-pointer foo.cpp
ASAN_OPTIONS=verbosity=1 ./a.out &> foo.log || true
./debian/qualify-clang.sh: line 634:  4281 Segmentation fault      (core dumped) ASAN_OPTIONS=verbosity=1 ./a.out &> foo.log
if ! grep -q "Init done" foo.log; then
    echo "asan verbose mode failed"
    cat foo.log
    exit 42
fi
asan verbose mode failed
