[Swift-user] Correction: Problem exists in 0.92 binary release as well

[Michael Wilde]

Dear Users,

We have found that the problem I pointed out in the March 31 message below also exists in the 0.92 binary release.

The symptom is that in certain cases of arrays that are computed within a script and iterated on later in the script using foreach, iterations of the foreach are executed twice.  This was not detected earlier because most scripts iterate over constant arrays, or arrays that are set by variants of readData.

We hope to correct these problems with a 0.92 fixed release.  Until we post that, use Swift 0.91 if you suspect that these or related synchronization bugs may be affecting your script's behavior.

We're very sorry that this slipped past our testing.

- Mike

Subject: [Swift-user] Problem in 0.92 source branch - do not use till	corrected

Dear Swift Users,

On March 29 we discovered that the Release 0.92 branches of the Swift and CoG trees were changed after the release and a concurrency bug was introduced. If you are running Swift from this *source code* base, please revert back to a known-working release such as the 0.92 binary release if at all possible.

We're working on restoring the 0.92 SVN branch to the correct state and will report back to this email list when that is done.

- Mike
