I used `wasm-reduce` on the `.ll` file and it looks like you were correct. The
result was:
```
target datalayout =
"e-m:e-p:32:32-p10:8:8-p20:8:8-i64:64-f128:64-n32:64-S128-ni:1:10:20"
target triple = "wasm32-unknown-emscripten"
define void @_ZN6Magnum5Trade12GltfImporter6doMeshEjj(ptr %agg.tmp4.i.i.i.i.i)
personality ptr null {
entry:
%0 = load i64, ptr inttoptr (i32 -16 to ptr), align 4
store i64 %0, ptr %agg.tmp4.i.i.i.i.i, align 8
ret void
}
; uselistorder directives
uselistorder ptr null, { 1, 2, 0 }
```
It looks like there is a -16 to ptr cast in there. I've ask the reported to
try running with `-fsanitize=undefined` and `-fsanitize=address`. Do you think
those will catch this kind of thing?
