[swift-build-dev] SwiftPM Boostrap Crash

[Ryan Lovelett]

I'm now convinced there is some sort of setting/folder being cached
somewhere that is causing this. I have 2 Macs (a work one, and a
personal one). Doing the same steps with the same code revisions checked
out on my work one triggers this crash; my personal one works as
expected.

Same result regardless of whether I run it like this:

$ cd ~/Source/swiftpm
$ Utilities/bootstrap
--sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk
--swiftc=/Users/lovelett/Source/build/Ninja-DebugAssert/swift-macosx-x86_64/bin/swiftc
--sbt=/Users/lovelett/Source/build/Ninja-DebugAssert/llbuild-macosx-x86_64/bin/swift-build-tool
--build=/Users/lovelett/Source/build/Ninja-DebugAssert/swiftpm-macosx-x86_64

💥

$ export
PATH="/Library/Developer/Toolchains/swift-latest.xctoolchain/usr/bin:$PATH"
$ cd ~/Source/swiftpm
$ Utilities/bootstrap

💥
