OS: 10.12.6 (16G29)
Steps:
1) Checkout swift and build master branch
git clone GitHub - apple/swift: The Swift Programming Language
./swift/utils/update-checkout --clone
2) Edit swift/utils/build-presets.ini to remove tests
[preset: buildbot_osx_package]
mixin-preset=
mixin_osx_package_base
mixin_lightweight_assertions
...
3) Execute ./swift/utils/build-toolchain local.swift
4) Execute n sample swift package in Xcode:

Stack dump:
0. Running pass 'Module Verifier' on function '@_FUNCTION_NAME_'
Does anyone know how to turn off module verifier or fix the above error (I
do not see the "-disable-llvm-verify" option with swift/swiftc command
line)?
