Thanks for letting me know. That version hasn't made it to testing yet, but I can confirm installing it from unstable fixes the crash.> > The upstream Chromium bug mentions the assert is also present in libc++,However, I noticed that the solution was to provide a custom optional header with the assert commented out. I just want to let you know that dereferencing an empty optional is undefined behavior: https:// en.cppreference.com/w/cpp/utility/optional/operator*
yet does not trigger.I think it would be safer to switch back to libc++ as I get the feeling libstdc++ is not really supported by upstream. Please reconsider.
Unfortunately, both library options have their own similar issues. Gcc/libstdc++ *is* supported upstream, it's just not their primary compiler. As upstream moves on to newer version of clang/llvm, we end up needing libc++ workarounds very similar to the <optional> header workaround due to older version of clang++ in debian. Eg,
