-d:ssl --threads:on --path:"src" # ARC: ORC cycle collector crashes under async wire-protocol load # (markGray/trace SIGSEGV, triggered from core/server.nim handleClient). # Still reproducible as of 2026-07-30 (Nim 2.2.10) — reproducer: # tests/orc_repro.py. Bisected: 200 pings + 200 SELECTs over TCP are # fine; the server dies somewhere between 20 and 500 sequential INSERTs. # Three root-cause attempts failed (callback cycle breaks in ed5a719, # {.cursor.} on ExecutionContext.registry, guarding ctx.onChange) — this # points at a deep ORC+async issue (possibly upstream Nim), not a single # app-level cycle. ARC is stable for the TCP server + HTTP worker mix. --mm:arc
