  • SR-6541 Swift Compiler Fills Memory Until Computer Crashes

Issue Description:

Try and compile the following Swift source:

struct Container {let string = "yes"}
let optionalContainer: Container? = Container()
let optionalString: String? = "toto"

switch optionalString {
case optionalContainer?.string?: ()
default: ()
}

The compiler crashes with a segfault.

PR #14798 should address this and it's merged into master. Thanks for reporting @Frizlab! Please use next available nightly build to verify.

@xedin Tested with latest nightly, no problem with compilation. SourceKit still crashes when code is put inside a Playground. No problems at all when run in a normal Command Line project.
