Update to MacOS Sequoia Version 15.4 (24E248) broke dmd and ldmd2 for me

[Christian Köstlin]

Hi,

I just updated to said version on Apple silicon and neither dmd 
nor ldmd2 work anymore for me (as installed by the dlang install 
script https://dlang.org/install.html, which in turn used 
dmd.2.111.0.osx.tar.xz and ldc2-1.40.1-osx-arm64.tar.xz).
On one hand I hope this is a local problem of mine, on the other 
hand I would like to ask here, if anybody else experienced/s this?

Some more details:
dmd and ldmd2 crash directly for me on invocation (even without 
arguments) (lldb blaims something in   * frame #0: 
0x0000000199ee4bf4 libsystem_pthread.dylib`pthread_getspecific + 
4 for both binaries).
ldc2 compile a simple hello world, but the executable crashes on 
the same "line".

Kind regards,
Christian
