Critical: Crash before main() on macOS 15.4 RC

[s-ludwig]

In the latest upcoming macOS update, any D application currently crashes during runtime initialization. I'm struggling to get a proper stack trace, but it looks like a null pointer dereference in pthread_getspecific. The only usable stack trace that I could get from one binary was this:
