I believe your last pull request fixed the bug in master branch. I just did not get any chance to make a build yet.

I believe your last pull request fixed the bug in master branch.

Indeed, the error doesn't occur with HEAD of master branch.

I just did not get any chance to make a build yet.

Looking forward seeing a new build soon. Thanks for your efforts.
