Are there any other threads in your program?
In other parts of the code, concatenation operations are all
failing with same error. I need guidance to get out of this
situation. My assumption was that as long as there is empty heap
memory, concatenation operation would succeed always. But, it

Is this error related to me? Is it a programmer error? Is it a

would work without a problem.

If you are OK with just a range spanning the two or more strings,

It's worth pointing out that Appender supports ~= so it's very
easy to swap it in, replacing builtin concatenation.
This works since 2.062 AFAIK. So is still quite new.
