Product:Developer Tools Product Version:Xcode-7 (7A176x)
Classification:Other Bug Reproducible:Always
 
Summary:
option-clicking a generic type with a space before the bracket crashes SourceKit.

Steps to Reproduce:
1. Type the following in a playground:

```swift
/// Some documentation.
func someFunc <A>() -> A {
    fatalError()
}
```

2. Option-Click the “A” in `<A>`.

Expected Results:
QuickHelp popover should display presenting “Some documentation.”.

Actual Results:
SourceKit either crashes or displays the popover presenting “No Quick Help”.

If SourceKit doesn’t crash on the first try, usually it does after another few tries.

Fixed in Xcode 7 Beta 6

The day after I filed this, Xcode 7 Beta 6 came out and this was no longer an issue.
