sys-info before 0.8.0 uses a static, global, list to store temporary disk information while running. The function that cleans up this list, DFCleanup, assumes a single-threaded environment and will try to free the same memory twice in a multithreaded environment. This results in consistent double-frees and segfaults when calling sys_info::disk_info from multiple threads at once.
