Multilingual systems are prevalent and broadly impactful, but also complex due to the intricate interactions between the heterogeneous programming languages the systems are developed in. This complexity is further aggravated by the diversity of cross-language interoperability across different language combinations, resulting in additional, often stealthy cross-language bugs. Yet despite the growing number of tools aimed to discover cross-language bugs, a systematic understanding of such bugs is still lacking. To fill this gap, we conduct the first comprehensive study of cross-language bugs, characterizing them in five aspects including their symptoms, locations, manifestation, root causes, and fixes. Through detailed analysis of 400 cross-language bugs in real-world multilingual projects classified from 54,356 relevant code commits in their GitHub repositories, we revealed not only bug characteristics of those five aspects but also how they compare between two top language combinations in the multilingual world (Python-C and Java-C). In addition to the empirical findings as well as its enabling tools and datasets, we also provide practical recommendations regarding the prevention, detection, and patching of cross-language bugs.

This room is located outside Clarion Hotel
This room is located in the Pirsenteret (The Pier Center) convention center. It is just outside the hotel, on the back, towards the fjord.
You should be able to go through the emergency exit at Clarion, just on the side of the Cosmos 3 wing, which will be bring you close to Pirsenteret.
The entrance to the center is from here:
