Hi, Could you please provide a reproduction scenario?

[phil-mitchell]

Not particularly. We saw this once in a timing-dependent scenario. However, it's pretty obvious what the problem is.

[phil-mitchell]

When will a release be created with this fix?

[alexpenev-s]

The latest release is 0.15; it was released about a week ago and it contains the fix.

[phil-mitchell]

Thanks. I did not see a v0.15.0 tag in github, so I was not aware of the new release.

We see a issue with following stack. We are running a version 0.13.0. Could the following stack might be due to same issue.
