Describe the bug
ASAN detects multiple memory safety violations in perf_profile_connector.cc including stack buffer overflow and undefined behavior due to misaligned memory access. The ASAN crash reports that stack_trace_key_t structures require 8-byte alignment but are being accessed at misaligned addresses, causing undefined behavior when reading BPF map data.
To Reproduce
Steps to reproduce the behavior:
- Build
stirling_wrapper with --config asan
- Run
stirling_wrapper with default sources (includes PerfProfileConnector)
- Let it run for ~2 minutes to allow perf profiler to collect stack traces
- Observe ASAN violations and program crash
Expected behavior
The perf profiler should run successfully under ASAN and not exhibit memory safety issues
