Bug hunting: Seg fault in lattice disorder Monte Carlo code (written in C) Wr

By Susanne Wallace, Anna Brown, Lewis Irvine, William Saunders and Paul Secular. As part of the Bath debugging workshop we attempted to find the cause of a segfault in a lattice disorder Monte Carlo code written in C. We were working without a known solution as recent unrelated additions to the code had fixed the bug without revealing why. We were able to find the cause of the segfault using memory checking and debugging tools to narrow down the location of the bug, with print statements to finish.

"We are in a position to fundamentally reorganise the heart of the software. By doing so, this will enable us to maintain the software into the future and facilitate the process of adding new functionality to the software ... SSI can assist in having software usable by others not just for a few months or a year, but rather for a much longer software lifetime"
