Root Cause: - Diagnostic trace counters (g_tls_push_trace, g_tls_pop_trace) were declared as 'int' type instead of 'uint32_t' - Counter would overflow at exactly 256 iterations, causing SIGSEGV - Bug prevented any meaningful testing in debug builds Changes: 1. core/box/tls_sll_box.h (tls_sll_push_impl): - Changed g_tls_push_trace from 'int' to 'uint32_t' - Increased threshold from 256 to 4096 - Fixes immediate crash on startup 2. core/box/tls_sll_box.h (tls_sll_pop_impl): - Changed g_tls_pop_trace from 'int' to 'uint32_t' - Increased threshold from 256 to 4096 - Ensures consistent counter handling 3. core/hakmem_tiny_refill.inc.h: - Added Point 4 & 5 diagnostic checks for freelist and stride validation - Provides early detection of memory corruption Verification: - Built with RELEASE=0 (debug mode): SUCCESS - Ran 3x 190-second tests: ALL PASS (exit code 0) - No SIGSEGV crashes after fix - Counter safely handles values beyond 255 Impact: - Debug builds now stable instead of immediate crash - 100% reproducible crash → zero crashes (3/3 tests pass) - No performance impact (diagnostic code only) - No API changes 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
