Hi Eric,

Can you check whether what you're building on has this commit? https://github.com/apple/swift-package-manager/commit/0268214b5477ca338b502c90aaa3e9ba50b68e18 <https://github.com/apple/swift-package-manager/commit/0268214b5477ca338b502c90aaa3e9ba50b68e18>

There was a truncation of a bit pattern that was causing a trap on arm.

It looks like you're using qemu, so it's possible that it's handling the trap strangely.

Also, for arm-specific build issues and the like, the swift-arm slack channel may be helpful http://dev.iachieved.it:9909 <http://dev.iachieved.it:9909/>

- Will
