--- Comment #2 from Milian Wolff <mail at milianw dot de> --- As I said, >99% of the samples point to this backtrace: ``` <our code> __sanitizer_ptr_cmp __asanCheckForInvalidPointerPair __asanCheckForInvalidPointerPair __asan::IsInvalidPointerPair __asan::GetGlobalAddressInformation(unsigned long, unsigned long, ...) __asan::GetGlobalsForAddress(unsigned long, __asan_global*, ...) __asan::isAddressNearGlobal ``` if you want per-line cost attribution, I'd first have to compile the sanitizer runtime with debug symbols. If you really need the `perf report` output instead (why?) I can redo the measurement again.
