OK, thank you Mike I'll never do that again.

It's quite unexpected for me that nobody give me some
help about usage of AA in shared library. Nobody use shared 
library? Nobody use AA?
Post with trivial questions about OpAssign gets many answers.
Even post about changing logo color from red to blue gets almost 
50 replies.
With all rules of decorum I post reproducible source code and ask 
any help.
Where is language community?
