Package: rustc Version: 1.28.0+dfsg1-2 Severity: critical Build anything with the rustc compiler for i386, and the result will contain SSE2 instructions. This means rust-based packages don't support the full range of what the i386 Debian architecture supports.
Specifically, this is the main cause for #908396/#908449.
