I'm pretty new to LLVM so I hope I'm reporting this correctly. I never saw an error like this before and it said I should report it.
**The command:**
`/opt/homebrew/opt/llvm/bin/llc -filetype obj test.bc -o test.o`
**LLVM version:**
```
/opt/homebrew/opt/llvm/bin/llc --version
Homebrew LLVM version 19.1.3
Optimized build.
Default target: arm64-apple-darwin24.0.0
Host CPU: apple-m1
```
**The LLVM IR:**
```llvm
; ModuleID = 'test'
source_filename = "test"
%struct.anonymous = type { i32, [7 x i8] }
define i64 @main() {
entry:
%list = alloca [3 x %struct.anonymous], align 8
store [3 x %struct.anonymous] [%struct.anonymous { i32 5, [6 x i8] c"hello\00" }, %struct.anonymous { i32 2, [6 x i8] c", \00\00\00\00" }, %struct.anonymous { i32 6, [6 x i8] c"world!" }], ptr %list, align 4
br label %return
return: ; preds = %entry
ret i64 0
}
```
**The error report:**
```
LLVM ERROR: Invalid size request on a scalable vector.
