CC @brson @alexcrichton - cross builds to Android core dump with an LLVM assert in this rustup from March 18th to March 24th.

[alexcrichton]

This may be somewhat related to rust-lang/rust#32360, although I'm not sure.

Also cc @eddyb, looks like lots of the MIR trans changes landed in that windows?

[eddyb]

@larsbergstrom Do you have a backtrace? My wild guess is that our casting of imports from multiple sources is biting us here, e.g. something is trying to modify attributes on a cast function pointer instead of the function declaration itself.

[larsbergstrom]

Eddyb is hoping this might be rust-lang/rust#32503

[nox]

I've bumped the nightly to a more recent one, but now it is blocked on Manishearth/rust-tenacious#16.
