osgText::TextBase function computePositionsImplementation() set "_offset" as a worng value.

I have create a osgText::Text object with empty text and setAlignment as LEFT_BOTTOM_BASE_LINE, then getBoundingBox will get a very large Y value.
I maybe found the reason right here:

The member "_lineCount" type is "unsignel int", it will be 0 when text is empty, unsigned 0 - 1 will got a very large positive number.
member "_offset" will be make transalte for member "_matrix", and the "_matrix" will be use at computeBoundingBox.

OSG Version: 3.6.5

That does look like a bug, with the code assuming that _lineCount is >= 1, changing the code to check for this condition, or use a min(_lineCount, 1) in stead of the _lineCount would resolve this issue.

Thanks for your reply, and I wonder if you will still release a version to fix known bugs? or just fix these issue by ourselves?
