  • SR-9299 "\r\n".replacingOccurrences(of: "\n", with: "_") crashes the program

Issue Description:

I installed the 4.2 CONVERGENCE branch for Ubuntu 18.04 (August 8, 2018)

I have a 100% reproducible runtime crash in a compiled swift program when using carriage return characters (also linefeeds, I didn't test others) in this line:

var logOutput = received.replacingOccurrences(of: "\r", with: "\\r")

Notice the first parameter is the problem. \r or \n crash at runtime. This does not happen in the REPL or on macOS.

Can you attach the whole program?

Comment by Timo Wälisch (JIRA)

Yes, I packaged a minimal project that causes the crash here and attached it.

This is my output:

> swift run
Compile Swift Module 'SR_8689_Sample' (1 sources)
Linking ./.build/x86_64-unknown-linux/debug/SR-8689_Sample
[1]    9690 illegal hardware instruction (core dumped)  swift run

It works perfectly fine if e.g. I remove the backslash of the first parameter.

Thanks for looking into.
