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
doesn't seem like so.

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

operation (string concatenation), and I assume/expect that it
would work without a problem.
reserving cuts down on the reallocations, but that only takes
some of the time. Appending a 1000-element int array is going
to go from a 16-byte block, to a 32-byte block, etc. up to a
4096 byte block. This involves roughly 8 reallocations per test.
