The task

The `build_trace()` function can allocate excessive memory when processing a malicious program that uses `op_mrupdate`. This causes the Hasher chiplet to generate an extremely large number of trace rows, leading to memory exhaustion (up to ~600GB). Additionally, when `core_trace_contexts` is empty, the trace…
