Turns out alignment on i686 MSVC is basically broken right now as MSVC is inconsistent. A 64bit integer on i686 can have a 4 byte alignment when clang and rust assume it is 8. This causes slice::from_raw_parts to panic since it will see 4 byte aligned values originating from the stack as misaligned.
For more info see rust-lang/rust#112480.
This makes is basically impossible to correctly call QuickJS functions on that platform. Any pointer returned from QuickJS might be misaligned according Clang. Working around this would be a lot of work for a quite old platform which could still be supported with a different toolchain. So I opted to drop support for i686 MSVC.
