Odin can achieve the same feature of checking memory leaks with it's custom allocator system. You can very easily have a custom allocator track the allocations of everything, including its source location. This is because Odin was heavily designed around custom allocators as a core feature.
And coupled with the implicit `context` system, it can very easily profile third party Odin code's allocations too!
