6621160755260): Some more information on the problem\:I would love to see if the
issue persists, if I disable memory management entirely; but
`threading/channels` requires me to use ORC or ARC, and does not compile if I
set anything else.
\<linebreak\>
I only just recently realized that the latest nim releases mention that I should
set `-d:useMalloc` if I'm also using `--threading:on` - I haven't been doing
that so far, even though it has been working using nim 2.0.2.
When I set `useMalloc` and run the same test, a different string (which I am
passing as argument to the worker thread) reads garbage out, and it soon after
that prints "malloc()\: unaligned tcache chunk detected" and crashes.
