Definitely core dumps are hooked to system-coredump. I don’t know this subsystem but I’m sure google knows. If I was like you, facing such a situation an unable to figure out where system-coredump throws the thing, I’d change kernel.core_pattern to a good old core.%p and have the core being reproduced.

Check kernel.core_pattern using sysctl -a Check ulimit -c Check if you have abrt installed..
