Package: libc++-13-dev
Version: 1:13.0.1-2
Severity: normal
Steps to reproduce:
File /tmp/a.cpp:
#include <stdint.h>
#include <stddef.h>
extern "C" int LLVMFuzzerTestOneInput(const uint8_t*, size_t) { return
0; }
Run clang++:
clang++-13 -stdlib=libc++ -fsanitize=fuzzer /tmp/a.cpp
Output:
/usr/bin/ld:
/usr/lib/llvm-13/lib/clang/13.0.1/lib/linux/libclang_rt.fuzzer-x86_64.a(FuzzerIO.cpp.o):

Older versions work fine:
clang++-11 -stdlib=libc++ -fsanitize=fuzzer /tmp/a.cpp && echo $?
