In large programs written in managed languages such as Java and C#, holding
unnecessary references often results in memory leaks and bloat, degrading significantly …

A big source of run-time performance problems in large-scale, object-oriented applications
is the frequent creation of data structures (by the same allocation site) whose lifetimes are …

Developers who set a breakpoint a few statements too late or who are trying to diagnose a
subtle bug from a single core dump often wish for a time-traveling debugger. The ability to …

Understanding the data structures in a program is crucial to understanding how the program
works, or why it doesn't work. Inspecting the code that implements the data structures …

Performance problems in managed languages are extremely difficult to find. Despite many
efforts to find those problems, most existing work focuses on how to debug a user-provided …

A calling context is an important piece of information used widely to help developers
understand program executions (eg, for debugging). While calling contexts offer useful …

Software corpora are crucial for evaluating research artifacts and ensuring repeatability of
outcomes. Corpora such as DaCapo and Defects4J provide a collection of real-world open …

Researchers have proposed many tools and techniques that work by traversing the heap,
including checkpointing systems, heap profilers, heap assertion checkers, and dynamic …

Software bugs cost time, money, and lives. They drive software research and development
efforts, and are central to modern software engineering. Yet we lack a clear and general …
