The system I can run 'rr' on is also x86-64 but has glibc 2.30, and
the issue isn't triggered by failing #345 (I've also switched to
testing based on git commits, at 69e84805 now). Back to brute-force

Best regards,


That stack trace looks very familiar. I'm about 90% sure that I saw the same error with Lua 5.3.5 (vanilla version, no patches) running on a microcontroller (so in very low memory conditions) using dlmalloc (bare metal, no OS). I doubt that I'll be able to reproduce the issue again, but I will try. I tried to debug the issue at the time, but without success.
