Please create a github issue with details of building your application and steps to reproduce the issue.

Do specify the commit hash, and if you have a branch, do mention that too.


I see you have re-sent this mail again to mailing list, did you try measuring the stack usage of threads using the PR mentioned in previous email threads?
