Memory-related program failures in multithreaded programs can be caused by a variety of bugs. Concurrency bugs can occur due to unexpected or incorrect thread interleavings during execution. Other kinds of memory bugs, such as buffer overflows and uninitialized reads, may also occur in multithreaded as well as single-threaded programs. Most prior techniques for isolating these bugs are speciali...

Context: Mobile applications support a set of user-interaction features that are independent of the application logic. Rotating the device, scrolling, or zooming are examples of such features. Some bugs in mobile applications can be attributed to user-interaction features. Objective: This paper proposes and evaluates a bug analyzer based on userinteraction features that uses digital image proce...

Assassin bugs (Stenolemus bituberus) hunt web-building spiders by invading the web and plucking the silk to generate vibrations that lure the resident spider into striking range. To test whether vibrations generated by bugs aggressively mimic the vibrations generated by insect prey, we compared the responses of spiders to bugs with how they responded to prey, courting male spiders and leaves fa...

During system call execution, it is common for operating system kernels to read userspace memory multiple times (multi-reads). A critical bug may exist if the fetched userspace memory is subject to change across these reads, i.e., a race condition, which is known as a double-fetch bug. Prior works have attempted to detect these bugs both statically and dynamically. However, due to their imprope...

Recurring bugs are common in software systems, especially in client programs that depend on the same framework. Existing research uses human-written templates, and is limited to certain types of bugs. In this paper, we propose a fully automatic approach to fixing recurring crash bugs via analyzing Q&A sites. By extracting queries from crash traces and retrieving a list of Q&A pages, we analyze ...
