- Fixed incorrect init_connections() call in test_etcp_simple_traffic.c (was calling server_instance instead of client_instance)
- Fixed double free in timeout_heap_pop() when handling deleted elements
- Enhanced NULL pointer safety in uasync_print_resources() by removing complex heap manipulation
- Added debug logging to timeout_heap_pop() for better error tracking
Test results: test_etcp_simple_traffic now passes without double free errors
✅ Fixed critical segmentation fault (SIGABRT) in test_etcp_two_instances
✅ Added comprehensive timer debug logging with DEBUG_CATEGORY_TIMERS
✅ Created uasync_print_resources() function for resource diagnostics
✅ Created utun_instance_diagnose_leaks() function for leak analysis
✅ Fixed cleanup order - cancel timers before destroying uasync instances
✅ Fixed timer cancellation to properly update counters
✅ Fixed socket cleanup to unregister from uasync before destruction
✅ Added detailed diagnostic output for memory leak tracking
✅ All tests now pass without crashes
Key fixes:
- Fixed use-after-free in test cleanup sequence
- Added proper timer leak detection and cleanup
- Enhanced debug capabilities for future debugging
- Fixed ETCP socket cleanup to prevent resource leaks
The test_etcp_two_instances now runs successfully without segmentation faults.
