[libc++] AddressSanitizer: alloc-dealloc-mismatch in std::logic_error

[nejati-deriv]

I get AddressSanitizer: alloc-dealloc-mismatch in clang-15 with -stdlib=libc++ -fsanitize=address flags and the whole program is this:

#include <stdexcept>
int main()
{
    std::logic_error{ "" };
}

Sanitizer error:

It only happens with -stdlib=libc++
Clang's version:

Ubuntu clang version 15.0.6
Target: x86_64-pc-linux-gnu
Thread model: posix

Could you provide the exact clang invocation you are using? When I try to reproduce it on Godbolt it works fine: https://godbolt.org/z/x5Wb9jTj6

I couldn't reproduce it on Godbolt either. It seems to be an issue in the libc++ that I am using.
This is the way I compile the program:

clang++-15 -stdlib=libc++ -fsanitize=address experiment.cpp

I am using latest version of clang-15 and libc++ in llvm official repository for ubuntu 22.04:

clang-15 is already the newest version (1:15.0.6~++20221129103233+088f33605d8a-1~exp1~20221129103332.101).
libc++-15-dev is already the newest version (1:15.0.6~++20221129103233+088f33605d8a-1~exp1~20221129103332.101).

We also hit this issue in the past. It appeared for us on clang 13 and 14 using the same official LLVM repository for Ubuntu 20.04. According to my colleague he was also able to reproduce this on Ubuntu 22.10 with clang 13 and 15.

Ok, so this seems to be some packaging/Ubuntu issue. I don't think I can help there.

If libc++ isn't a hard requirement libstdc++ can be used as a workaround.

Just had it again with clang-16 on Ubuntu 20.04: https://gitlab.com/hzdr/crp/alpaka/-/jobs/4799325263#L3287. But we get clang from LLVM's apt repo: https://apt.llvm.org/.
