I'm trying to parse tests form upstream swift repository and with swift-ast and found a crash of files https://github.com/apple/swift/blob/master/test/SILOptimizer/diagnostic_constant_propagation_int.swift and https://github.com/apple/swift/blob/master/test/SILOptimizer/diagnostic_constant_propagation.swift
This files are also attached in the archive.

I'm having the same problem when try to parse this file:
https://github.com/jpsim/Yams/blob/master/Tests/YamsTests/ConstructorTests.swift
Is there a fix for this or a way to work around?
