Build of 1.39.0 fails on x86_64 on `syntax` lib: `error:0:Type mismatch between [(); 96] and [(); 112] - sizes differ`

[barracuda156]

Not something wildly important for me, but presumably x86_64 builds were tested? I get an error building 1.39:

BUILD FAILED
make[1]: *** [output-1.39.0/rustc] Error 1

At first I thought maybe something in my patches caused a regression, but I rebuilt mrustc from da4075f (before my recent patches merged), and nothing changed, building rustc with it fails identically.

Removing that assert, the build fails further on:

Both failing asserts are x86_64-specific.

[thepowersgang]

Those asserts are size checks, which I've started just removing with patches in recent versions.
That said, I think the second type is the actual size - so that does imply that the size has increased since the last time a full 1.39 compile was tried.

[thepowersgang]

(Or, the sizes change on OSX)

That final error looks like an OSX specific piece of code triggering a missing typeid generation. It might be fixed with the 1.90 branch (when that is merged) as it seems familiar.
