I tried your code.
It's still possible that this is an application bug, of course (maybe in one of
the dependencies, if not in your application).

Ok, I will file an issue. I just wanted to rule out any application level
issues first. Did you try it on the code I sent or did you use some other
test case? Is there a test-suite in GHC that stresses the threaded runtime?

I was able to reproduce on GHC HEAD. With debug runtime I consistently get this
assertion error:

Unfortunately, it is present in 8.8.2 as well.

You should try with 8.8.2 which fixes a bug in the compacting GC (#17088).
When debugging it's a good idea to use the latest minor release of your GHC
version (8.8.2 in your case), as minor releases fix bugs and usually do not
introduce new ones as they don't ship new features.
If the problem sti
The way to debug these kinds of issues is to use gdb.
The best clue in your message seems to be "The GHC heap size is
restricted to a small size ~32MB using "-M32M" rts option.".
Good luck!

Hi,
While running a test-suite for the streaming library streamly I am
encountering a crash which seems to happen at random places at different
times. The common messages are:
* Segmentation fault: 11
* internal error: scavenge_mark_stack: unimplemented/strange closure type
