Three coupled changes that unblock the ecdsa quantum-circuit simulator's run on the C tier from neoblanka. 1. c/Makefile autodetects libgc-dev — if /usr/include/gc.h is present, the build links Boehm and defines USE_BOEHM_GC. Without GC, ul_free is a no-op (lumbda.h:35) and every allocation leaks; small REPL snippets work but workloads with thousands of envs OOM the process. Override with USE_GC=0 to force the malloc-only path for diagnostics. 2. c/main.c calls GC_INIT before init_symbols, then GC_disable. GC_INIT registers the stack base for conservative scan — without it some Linux configs miss roots. GC_disable is a deliberate stopgap: lumbda Values are NaN-boxed pointers that conservative Boehm cannot recognize as pointers, so live targets get reclaimed (env binding symbol payloads, SymbolEntry strings) and lookups fail with "undefined: <sym>". Reproducing this without GC_disable on the GC build: any sim.lsp call chain triggers the corruption after ~100 named-let iterations. Until tracing is precise, growing the heap is safer than wrong results. Long-running workloads run under ulimit -v. 3. c/builtins.c gains rename-file and delete-file matching the Python tier (lumbda.py:3468). sim.lsp's write-portal! pattern (write to .tmp, rename) needs rename-file to land cross-tier identical results. 4. tests/regression-named-let-leak.lsp + .sh pin four shapes that blew up ecdsa: the c/TODO-named-let-bytecode.md repro, the F1 shape from foxhop.net's lumbda-c-tier-leak-SP.md (12-line minimum), a 200-iter scaled variant, and a sim.lsp run-ops! mirror. Wired into root Makefile as regression-named-let-leak; added to test-all. Wrapper caps memory at 256 MB virt and 15s per tier so a leak regression fails the run instead of consuming host RAM. Known limits: - --fast JIT still has the named-let + inner user-fn call hang (separate TODO; tree-walker handles this fine). - GC_disable means the heap grows; workloads must bound their work budget. ecdsa's sim runs comfortably in 5 MB. Verified inside a 2G/2vCPU QEMU guest (foxhop.net ecdsa/vm-runner.sh): - test-c (tree-walker) — 35/35 PASS - bench-c (tree-walker) — score 18 matches Python tier byte-identical - F1 probe (tree-walker) — all four steps PASS
