Users must manually implement guard pages or canaries.\n\n## Proposal\nAdd optional stack overflow detection helpers:\n\n1. **Guard zone utilities**:\n   - `stackman_guard_init(void *stack, size_t size, size_t guard_bytes)` - Initialize guard pattern\n   - `stackman_guard_check(void *stack, size_t size, size_t guard_bytes)` - Verify guard intact\n\n2. **Stack usage tracking**:\n   - `stackman_stack_usage(void *stack_base, size_t size)` - Measure actual usage via stack painting\n\n## Benefits\n- Easier debugging of stack-related crashes\n- Production overflow detection\n- Helps users size stacks appropriately\n\n## Implementation\nCould be a separate header (`stackman_debug.h`) to keep core library minimal.\n\n## Related\ntest_04 already uses basic guard bytes for validation - could formalize this pattern.","author":{"url":"https://github.com/kristjanvalur","@type":"Person","name":"kristjanvalur"},"datePublished":"2025-11-16T19:14:48.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/14/stackman/issues/14"}
