I guess the issue is the following:

clang: ../llvm/llvm/lib/Target/AArch64/AArch64FrameLowering.cpp:2857: StackOffset llvm::AArch64FrameLowering::resolveFrameOffsetReference(const MachineFunction &, int64_t, bool, bool, Register &, bool, bool) const: Assertion `-ObjectOffset > (int64_t)AFI->getSVECalleeSavedStackSize() && "Math isn't correct for CSRs with FPAfterSVECalleeSaves"' failed. PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

I'll try to have a patch tomorrow.

Thanks, -Eli
