Summary:

I'm experiencing random crashes with Xcode 9 beta, while using the text editor.
This happens on some projects, when I try to command-click on a symbol.

Xcode simply quits, and no crash report is generated.

I can get more infos about the crash running Xcode in LLDB.
Attached is LLDB session log.

--------------------------------------------------

Steps to Reproduce:

In the text editor, command-click on a symbol.

--------------------------------------------------

Expected Results:

The symbol action popover should open.

--------------------------------------------------

Observed Results:

Xcode sometimes quit, without generating a crash report.

--------------------------------------------------

Version:

Xcode Version 9.0 beta (9M136h)
macOS Version 10.13 Beta (17A264c)

--------------------------------------------------
