[swift-corelibs-dev] Encountering "Constant strings cannot be deallocated"

[Alex Blewitt]

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.
