Hello! I have a test case that when run on Linux somehow encounters
the "Constant strings cannot be deallocated” fatal error thrown in
NSCFString.swift, as seen here:
https://github.com/apple/swift-corelibs-foundation/blob/master/Foundation/NSCFString.swift#L118
The test that does it is here:
Now there’s a lot to unravel here and I haven’t been able to quite isolate
it, but I thought perhaps someone here might know how that could path could
even be executed.
Thanks for any help!
Is this with a recent build? Do you know what commit the swift-corelibs-foundation is from? That might help nail down what is going on here.

Ah, sorry for now providing more info!
So the docker file that I am using to run the tests can be see here:

Can you file a bug at bugs.swift.org <http://bugs.swift.org/> with a minimal test case? It certainly sounds like a bug, and from the looks of the docker files, you're using the swift 4.0.2 release on Ubuntu 16.04.
If you can run the test under LLDB and put a breakpoint in that function, and get a backtrace (with 'bt') then it might be interesting to see where the deinit is being triggered, and give some kind of clue as to what is happening.

I haven’t been able to find a minimal test case, but at least the test case
I linked to reproduces every time.
I’m not sure I’ll have time to search for a minimal case today, and I leave
for vacation tomorrow 
perhaps when I get back.
I did at least file the bug report: https://bugs.swift.org/browse/SR-6422
