└─────────────────────────────────────────────────────────────────────────────┘
|
|
|
|
Bug: "free(): double free detected in tcache 2" SIGABRT crash
|
|
|
|
Root Cause:
|
|
1. MPSCQueue::drop() freed dummy node explicitly
|
|
2. HazardPointers::drop() tried to free it again from retired list
|
|
→ DOUBLE FREE
|
|
|
|
Fix: Never retire dummy node to hazard pointers
|
|
✅ Track dummy_node pointer in struct
|
|
✅ Skip retiring dummy in try_pop(): if head != self.dummy_node
|
|
✅ Free dummy once in Drop: Box::from_raw(self.dummy_node)
|
|
|
|
Validation:
|
|
✅ Valgrind clean (no leaks, no double-frees)
|
|
✅ AddressSanitizer passing
|
|
✅ 1000 iteration stress test passed
