Issue Description:

This commit:

pointfreeco/pointfreeco@4ea3311

Contains this code:

pointfreeco/pointfreeco@4ea3311#diff-7f12bec2f578f77c2b856d323cbeaab2R60

That crashes on Swift 4.2.1 in when built for release mode:

swift: /home/buildnode/jenkins/workspace/oss-swift-4.2-package-linux-ubuntu-16_04/swift/lib/SILOptimizer/Transforms/SILMem2Reg.cpp:879: bool (anonymous namespace)::MemoryToRegisters::promoteSingleAllocation(swift::AllocStackInst *, DomTreeLevelMap &): Assertion `isWriteOnlyAllocation(alloc) && "Non-write uses left behind"' failed.

You can reproduce with the following steps:

git clone https://github.com/pointfreeco/pointfreeco.git
cd pointfreeco
git checkout 7647c0c
make bootstrap
make linux-start

We were able to workaround the problem with this fix:

https://github.com/pointfreeco/pointfreeco/pull/375/files

Looks like it's the generic "A" that causes the issue.

@eeckstein, is this something that's been fixed in the 5.0 branch already?

Yeah, this looks like a dup of rdar://problem/44143761, which I fixed in b702f99
