I just spent all day migrating my 30,000-line Swift project to 2.0 and was rewarded with this lone error. Any clue what it means? Is it yet another internal error?

Assertion failed: ((IGF.IGM.DataLayout.getTypeSizeInBits(coercionTy) == IGF.IGM.DataLayout.getTypeSizeInBits(paramTI.StorageType)) && "Coerced types should not differ in size!"), function emitDirectExternalParameter, file /Library/Caches/com.apple.xbs/Sources/swiftlang/swiftlang-700.0.38.1/src/swift/lib/IRGen/IRGenSIL.cpp, line 908.

It appears to be crapping out on this perfectly harmless line of code (which compiled fine in 1.2), so I think it's the Swift compiler just crashing and burning like all during 1.0 Beta. Perhaps due to some project-complexity issue? Anyone else seeing problems like this already?

Another part of the error message is "Abort Trap 6" in "While emitting IR SIL function..."

Any clue what this means? My SceneKit app is dead in the water with this, under Swift 2.0b1.
