Hi,
I'm getting a weird crash in llvm optimizer:

`Exception thrown at 0x00007FF6C36EE4B8 in BitwigAudioEngine-ARM64-NEON.exe: 0xC0000005: Access violation writing location 0x0000000000000000`
I've a JIT engine using LLVM-19.1.3 on Windows ARM64.
Do you have anyidea what the problem could be based upon the backtrace?
Thanks!
