❌ CRASH: trading_engine (SIGABRT)
Fatal Error:
free(): double free detected in tcache 2
signal: 6, SIGABRT: process abort signal
Context:
- Occurs during lock-free atomic operations tests
- Memory corruption in concurrent data structures
- Indicates critical memory safety issue
Status: Tests aborted, unknown pass/fail count
⏸️ BLOCKED: Services (5 crates)
The following services timed out during compilation/testing:
- api_gateway
- trading_service
- backtesting_service
- ml_training_service
- e2e_ensemble_integration
Reason: Build lock contention + long compilation times

Critical Blockers
1. Data Crate - Compilation Failures (PRIORITY 1)
Issue: Missing fields in MarketDataEvent struct initialization
Fix Required:
// Current (BROKEN):
let event = MarketDataEvent {
symbol: symbol.clone(),
price: close,
volume: volume as f64,
timestamp: timestamp_nanos,
event_type: EventType::Trade,
// MISSING: high, low, open
};
// Fixed:
let event = MarketDataEvent {
symbol: symbol.clone(),
price: close,
volume: volume as f64,
timestamp: timestamp_nanos,
event_type: EventType::Trade,
high: close, // Add with placeholder
low: close, // Add with placeholder
open: close, // Add with placeholder
};
Files to Fix:
data/tests/parquet_persistence_tests.rs(5 instances)data/examples/convert_dbn_to_parquet.rs
2. ML Crate - 8 Test Failures (PRIORITY 2)
Categories:
- Model creation/initialization: 2 failures
- Feature extraction: 1 failure
- Training loop: 5 failures
Estimated Fix Time: 30-60 minutes per test = 4-8 hours
3. Trading Engine - Memory Corruption (PRIORITY 1 - CRITICAL)
Issue: Double-free in atomic operations causing SIGABRT Risk Level: CRITICAL - Production blocking Impact: Crashes entire test suite, indicates memory unsafety Investigation Required: Lock-free queue implementation audit
Comparison to Wave 5 Baseline
| Metric | Wave 5 | Wave 6 | Delta |
|---|---|---|---|
| Total Tests | 1,223 | 1,229+ | +6 |

Progress: Wave 6 improved pass rate by ~1% despite adding more tests
100% Pass Rate Goal Assessment
Goal Achieved: ❌ NO
Remaining Work:
-
Fix data crate compilation (BLOCKER - 0 tests run)
- Estimated: 15-30 minutes
-
Fix 8 ML test failures (NEAR-GOAL - 98.9% pass rate)
- Estimated: 4-8 hours
-
Debug trading_engine crash (CRITICAL)
- Estimated: 4-16 hours (memory corruption bugs are complex)
-
Complete service tests (BLOCKED)
- api_gateway: ~80 tests expected
- trading_service: ~50 tests expected
- backtesting_service: ~12 tests expected
- ml_training_service: ~30 tests expected
- e2e: ~22 tests expected
- Total: ~194 tests untested
Realistic Pass Rate Projection:
- Best case (all services pass): 99.5-100%
- Likely case (some service failures): 98.5-99.5%
- Worst case (trading_engine unfixable): 95-98%
Recommendations
Immediate Actions (Next 4 Hours)
-
Fix data crate compilation errors (30 min)
- Add missing OHLC fields to test fixtures
- Verify all parquet tests compile and run
-
Re-run complete test suite (60 min)
- Clear build locks:
killall cargo - Run overnight:
cargo test --workspace --release -- --test-threads=1
- Clear build locks:
-
Debug trading_engine crash (2+ hours)
- Run under Valgrind:
valgrind --leak-check=full target/release/deps/trading_engine-* - Isolate lock-free queue double-free
- Consider disabling test until fixed
- Run under Valgrind:
Short-Term (Next 24 Hours)
-
Fix 8 ML test failures
- Prioritize training loop tests (production critical)
- May require MAMBA-2 model fixes from prior agents
-
Complete service test execution
- Run services sequentially with 10-minute timeouts
- Document any new failures
Long-Term (Next Week)
-
Implement regression prevention
- Add pre-commit hook:
cargo test --workspace - CI/CD gate: 99% pass rate minimum
- Add pre-commit hook:
-
Memory safety audit
- Full Valgrind run on trading_engine
- Consider memory sanitizers (ASAN/MSAN)
Technical Notes
Build System Issues
- Cargo build lock contention caused timeouts
- Solution: Run tests with
--test-threads=1or sequentially
Test Environment
- Platform: Linux 6.14.0-33-generic
- Rust: 1.82+ (edition 2021)
- CUDA: RTX 3050 Ti (not used in unit tests)
- RAM: Sufficient (no OOM observed)
Warnings (Non-Blocking)
- data crate: 60+ unused dependency warnings
- ml crate: 15 unused imports, 10 unused variables
- Impact: None (warnings don't affect functionality)
