RocksDB SIGTRAP on Apple Silicon: Hardened libc++ vs Custom Aligned Allocators

Summary

RocksDB crashes with SIGTRAP (EXC_BREAKPOINT, brk #0x1) on Apple Silicon (aarch64-apple-darwin) when statistics are enabled. The crash occurs inside StatisticsImpl::recordTick or StatisticsImpl::recordInHistogram during normal database operations, including DB::Open.

The root cause is an incompatibility between Apple Clang's hardened libc++ bounds checking and RocksDB's custom cache-line-aligned allocator used by StatisticsData.
