Re: [swift-corelibs-dev] Encountering "Constant strings cannot be deallocated" in Linux foundation

I think that perhaps we have a problem with the retain count flags in the definition of CFSTR. Previously the pinned reference would prevent the deallocation. This may have gotten clobbered with the latest CF import. Sent from my iPhone > On Nov 29, 2017, at 7:55 PM, Brandon Williams via

Re: [swift-corelibs-dev] Encountering "Constant strings cannot be deallocated" in Linux foundation

Hey Tony, We were able to fix our crashes by avoiding our uses of `URLQueryItem`s. In one place I had to completely remove the use of `URLQueryItem`: https://github.com/pointfreeco/swift-web/pull/79/files#diff-293b73a926ba418bd9511ef735fc947cL147 And in another my colleague Stephen Celis

Hello all! We’ve been encountering this runtime error quite a bit recently, and we have no idea why. We’ve filed a bug and there’s one other on JIRA related to this, but both without any comments: https://bugs.swift.org/browse/SR-6422 https://bugs.swift.org/browse/SR-6398 We’re curious if

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

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:

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

Can you file a bug at 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

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. > On Nov 16, 2017, at 2:41 PM, Brandon Williams via swift-corelibs-dev > wrote: > > Hello! I have a test case that when

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

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:
