Thanks for the report. Do either of `p err` or `v err` work?

Good question, I unfortunately don't have the code in the exact state to trigger that specific bug anymore (I fixed the issue with gdb/swift demangle...) but will see if I can make it happen again. I basically run into tons of asserts currently (read: every single time I run lddb currently) with both 5.3.3 and 5.4 dev snapshot on Linux, I'd be happy to capture additional information (or providing you with source snapshot/branch that reproduces - I'm just working on SwiftNIO so it can be freely shared, but a few prerequisites on the runtime environment (Ubuntu 20.04, updated kernel to 5.11 and liburing installed) - let me know if that is something you want to pursue and I will simply branch/tag the WIP if you want a full reproducible environment.
