clang-23-compiled executable segfaults, while llubi interprets the same IR successfully

I found a case where llubi can interpret the IR successfully, but the executable generated by `clang-23` crashes with a segmentation fault.

IR program:

```llvm
target datalayout = "e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:64:64-i64:64:64"

define i32 @main() {
%alloca = alloca [2 x i32]
store <4 x i32> zeroinitializer, ptr %alloca, align 8
store [2 x i32] [i32 1, i32 1], ptr %alloca, align 8

%load1 = load <4 x i32>, ptr %alloca, align 8
%load2 = load <4 x i32>, ptr %alloca, align 8
%load3 = load <4 x i32>, ptr %alloca, align 8
%load_arr = load [2 x i32], ptr %alloca, align 8
ret i32 0
}
```

`llubi` interprets the program successfully:

```
Entering function: main
%alloca = alloca [2 x i32], align 8 => ptr 0x8 [alloca]
store <4 x i32> zeroinitializer, ptr %alloca, align 8
store [2 x i32] [i32 1, i32 1], ptr %alloca, align 8
%load1 = load <4 x i32>, ptr %alloca, align 8 => { i32 1, i32 -289830082, i32 1, i32 -399511892 }
%load2 = load <4 x i32>, ptr %alloca, align 8 => { i32 1, i32 -132966042, i32 1, i32 1094190734 }
%load3 = load <4 x i32>, ptr %alloca, align 8 => { i32 1, i32 -1670034957, i32 1, i32 -899485425 }
%load_arr = load [2 x i32], ptr %alloca, align 8 => { i32 1, i32 1 }
ret i32 0
Exiting function: main
```

However, after compiling the same IR with `clang-23` and running the generated executable, the program crashes with the log "Segmentation fault (core dumped)".
